Co-worker behaviour suddenly changed when I got pregnant. Am I overthinking this ?

I’d really appreciate some outside perspectives because I don’t know if I’m being overly sensitive or if something genuinely feels off.

This is my first baby and I’m currently 26 weeks pregnant. I’m also in a committed long-term relationship and we were both really happy when we found out.

However, before I got pregnant, my co-worker had been going through issues with her husband cheating. For around 6 months, Monday to Friday, I listened to her talk about it constantly. I supported her, listened, gave advice and tried to be there for her.

I’ll be honest — hearing about cheating every day actually started to affect me mentally. I found myself questioning my own relationship and worrying about things I hadn’t previously worried about. It even caused arguments between me and my partner, which looking back, only really started happening during that period of constantly hearing about her situation.

Then I found out I was pregnant — and that’s when things seemed to change.

When I first told her, she said she was happy for me. However, her energy and reactions didn’t always match that. Whenever I spoke about my pregnancy, she would often:

  • Redirect the conversation back to when she was pregnant (she has a 3-year-old daughter)
  • Talk about her own experience instead of engaging with mine
  • Bring up trauma from her previous pregnancy or relationship issues
  • Say that my pregnancy made her think about how happy she was when she found out she was pregnant, before her husband cheated on her

For example, I’d mention something positive about my pregnancy and she’d end up crying and talking about:

  • Her partner cheating when she was pregnant
  • Her previous pregnancy experience
  • Her relationship issues

It started to feel like my pregnancy moments were being turned into her experiences.

Then something else happened which made me question things further.

I waited until I was around 20 weeks before telling most people at work. Around that same time, she then announced she was 1–2 weeks pregnant and went around telling the same coworkers I had just told.

I also found it odd because she said she was surprised she was pregnant and kept asking her husband “what did you do?” as if it hadn’t really been planned.

She then started:

  • Asking which private scans I had booked
  • Asking where I went for my gender scan
  • Booking the same scans shortly afterwards

Unfortunately she then went on to miscarry, which was obviously very sad.

However, after this, her behaviour seemed to shift again. She suddenly started:

  • Wanting to bond with me over pregnancy
  • Talking more about babies and pregnancy with me (which she hadn’t really done before)

Then recently, she told me that two of her family members had announced pregnancies and she is now trying to get pregnant again.

She has even asked me:

  • When I conceived
  • My due date timing

She mentioned she wants to time it so she can also be on maternity leave next summer, as I am going on maternity leave in June for the summer this year.

There have also been other comparisons:

  • When I mentioned wanting a natural birth, she suddenly wanted the same
  • I said I might keep the gender a surprise — she then said she would too
  • I mentioned hoping my partner might propose around my baby shower/30th — she then immediately spoke about renewing vows and her own 30th (which is 2 years away)

It just feels like whenever I share something about my pregnancy or future, she brings it back to herself or mirrors it.

I’m still being friendly and professional, but I’ll be honest — I don’t really like her anymore. I find her draining and the comparisons uncomfortable, especially during what should be a happy time for me.

Am I overthinking this, or does this sound like someone reacting to my pregnancy?

Would really appreciate honest opinions.

I would stay friendly, but spend as little time with her as possible.

PollyBell · 02/04/2026 23:09

This seems over dramatic from both sides just stick to work

ktopfwcv · 03/04/2026 00:51

It's the "I'll be honest" in both posts.
Definitely AI, all 3 of them.

She's batshit. You're slightly less so. I get that you're excited about your first child but saying that she "Talks about her own experience instead of engaging with mine" is a bit much. Other people are never going to be as interested in your baby as you are, this lunatic aside.

Absolutely this. She’s a pain in the arse and mental. You’ve also been overthinking this from day dot. And if you talk about your pregnancy and she’s also been pregnant she’s probably going to talk about that? That’s how conversation works.

Exactly. This is mad, OP. I don’t even give the behaviour of my longtime friends, whom I love, this much thought. When I had a colleague having a hard time, I listened, absolutely, but I didn’t map their relationship issues onto my own life.

Do you not have that many other people in your life that you talk to?

Are the other threads written by AI too?

Thank goodness it's not just me.
Honestly, so fucking sick of AI/Chat GPT whatever.
Tune right out and stop reading as soon as it becomes clear.

CamillaMcCauley · 03/04/2026 02:31

She sounds like she’s had a bloody tough year and is struggling.

kiwiane · 03/04/2026 02:38

She’s a colleague and you need to find ways to have a break without her. If she’s constantly distracting you whilst you’re working then seek help to give you some peace. Stop engaging so much with her; you’re not her counsellor and you won’t want daily contact when you have a new baby.

Stickytoffeetartt · 03/04/2026 04:33

She will probably text you every day when you're on leave asking is the baby here yet 😆 block her now!!! She sounds like a psycho , her poor dh and dc . She obviously faked the pregnancy for attention as she didn't like you stealing the limelight. Completely unhinged behaviour. At least you only have to put up with her for another 10 weeks or so!

gerispringer · 03/04/2026 04:39

When are you getting any wirk done?

Malasana · 03/04/2026 06:38

Do people really share this much information with colleagues during the work day?
When do you ever get your work done?
You’ve overshared inappropriately in the workplace and this is the result.
Back away, stop with all the personal stuff and interact with her professionally from now on.

Lifewontbethesame · 03/04/2026 07:08

Do either of you actually get any work done at work? My god who has time for all that personal chat. Just keep your head down, get on with your job and stop discussing your pregnancy 'moments' at work. Sounds like you've both massively over shared.

TheBeaTgoeson1 · 03/04/2026 07:55

What’s with all the bullet points?

Youzername · 03/04/2026 08:23

She’s a drainer, there are loads of them around.

I’d stop sharing so much information, keep it polite and professional, and wind this friendship down.

AI.

The OP has two other threads in a similar vein about people hogging her pregnancy.

Mcoco · 03/04/2026 10:25

Ask her if she has ever watched single white female. She sounds unhinged. Just avoid her something definitely wrong.

MyTrivia · 03/04/2026 10:27

Why does this post read like it was written by AI?

CaragianettE · 03/04/2026 11:20

YABU to write such a long post with quite so many bullet points! Focus on your own life and don’t put so much mental energy into her and her behaviour.

Sunshineandgrapefruit · 03/04/2026 15:34

Stop sharing. I would also be surprised if she actually had been pregnant. The way you described it sounded like she was just jumping on the bandwagon. It's not possible to know at 1-2 weeks and even if she meant 5-6 weeks, I have never heard of anyone telling colleagues then, and most wouldn't even tell family.

TheIceBear · 03/04/2026 16:00

She sounds quite immature and self centered and hard to listen to and many of the things you have mentioned sound abnormal it would be very hard to listen to someone harping on about being cheated on constantly and relaying that back to your pregnancy is tone deaf and ridiculous. However what do you mean “suddenly wanted a natural birth?” I don’t really get that I mean what was she saying before that if she was only newly pregnant . Or that she wanted to keep the gender a surprise I mean who cares that’s not unusual at all ? To suggest she is copying you in that regard sounds a bit childish . I am on mat leave at the moment and I didn’t have such detailed conversations with my colleagues about my pregnancy. It’s just weird
