SIL sharing pregnancy news behind our backs (were only telling family)

[Carysmatic]

Yesterday while at a music festival my DH organised and performed at, I was approached by a woman who I had never met before in my life who came up to me and said "congratulations we hear you're pregnant" followed by "oh sorry do you know who I am?" Turns out she's a good friend of my SIL, who we only told last week, who knew we were only telling family. I'm only 7+4weeks so it's really early days. Now my SIL is known for being increasingly petty and I know she's been moaning to this friend about the fact that I'm pregnant. She has one DS but has put herself in competition with her siblings to do things first and made it clear she wanted to have her second before me and DH even had our first! Once she found out we were trying she went behind mine and my DH back and was telling people that I was forcing my DH into trying for a baby when he wasn't ready. Which is total crap, me and my DH decided to try together. I am so fed up with her crap and this feels like the final straw! AIBU?

Alsohuman, morning sickness started really early for me, around the time you'd normally test. The test just confirmed what I already knew.

My SiI did this. In my case I only told her as she came round and I had really bad morning sickness. I was waiting until the scan to tell my own parents as my father was very ill, and I didn’t want to tell him until I had passed the most risky time for miscarriage. I explained to SIL that I didn’t want to tell anyone, and why.
She went off and told friends of hers, who then told friends of mine ! So I had one of my oldest friends calling me with congratulations! I’d had one miscarriage and was 40, so higher risk.
Many years later it still makes me angry, and I stopped trusting her. She only had to wait a few weeks, it wasn’t like a secret you have to keep forever.

Alsohuman - A stomach upset covers not drinking and being sick - although I don’t recall morning sickness as early as seven weeks. You never have to tell anyone anything.

Well you've been pretty lucky. The peak time for sickness is 6-12 weeks but many suffer for much longer. I had HG and was vomiting 20+ times a day from week 4 until 16. I lost 20lbs and had to cancel a holiday to visit family. No-one would have bought a "stomach upset" excuse for 3 months.

OP - your SIL is being petty so I'd cut down on the information you tell her - let her be the last to know

If the debate about the onset of sickness is over, I’ll repeat the important bit. You don’t have to tell anyone anything.

When you tell people that you are ttc you just out yourself under even more pressure imo.
Then you feel even more shite when they keep asking and it isn't happening.
