I don't know if I'm overreacting to this due to pregnancy hormones, as DH thinks I am, so thought I'd ask for opinions... This may be long, sorry!
I live on the other side of the world to my family, and I've been feeling a bit rotten (sickness, really, really tired) with this pregnancy (my 4th) so DH suggested I tell a couple of my close friends here to get a bit of support. We've never told anyone before the 12 week scan before as I get a bit paranoid about jinxing it - silly I know but I worry a lot! But as my friends here are like my family and I knew they would help me if I needed it I thought it was a good idea.
So I told two of my friends when I was about 8 weeks, who have been great, really happy for me and helping out with school run etc.
Anyway, a good friend came round for the morning, who has been very supportive in the past and we help each other out with babysitting, moving house etc, although as we live on opposite sides of the city we don't see each other as much as we used to. In the middle of a conversation I had to run off to be sick 
, so I figured I should tell her really, and was kind of planning to anyway. However, she reacted in a really negative way, saying that she wouldn't want more kids (she's got 3 herself), she likes her own life, rather me than her, which is fair enough, but she is 10 years older than me and I did point out I was actually happy to be having a 4th dc. She started quizzing me about where they were going to sleep and I said they would share, 2 in each room, as they are all close in age, to which she said it was cruel to make them share as she believes kids need there own rooms...
This isn't the bit that has really upset me though. I get a bit paranoid about things going wrong with the pregnancy, and I don't really like many people knowing before the scan in case something is wrong, so I told her to please not tell anyone at all and to keep it quiet until after the scan, and she said of course she wouldn't tell anyone... Fast forward to a week later and I go round a friends house, only for her to say "so I heard your good news!", to which I was a bit 
obviously! I obviously knew where she must have heard it as she doesn't know the other two people I told, and asked her had she seen our friend. No, apparently the moment my friend had left my house she had texted our other friend saying "don't is pregnant!". My other friend said she was really shocked she'd been texted it as she'd presumed I'd wanted to tell her myself, and had texted pretty much that back, but hadn't had a reply. She said that when she was pregnant this same friend had told our whole baby group despite being told not to, which I had completely forgotten . She has just told me that take it as a lesson learned that you can't trust her with anything that you want kept a secret.
I haven't heard anything from this friend since, but I'm sure I will in the next couple of weeks and I really don't know what to say to her. Do I mention it and tell her I was a bit hurt, or do I just pretend it didn't happen? She is the kind of person to just shrug stuff off so I don't know whether I should just leave it?
So am I being unreasonable feeling quite hurt and a bit betrayed by this? I am feeling very hormonal and I am really worried about my 12 week scan this week in case something isn't right, I'm already feeling sick about it (I had a bit of a horrendous scan with dc3, they thought something was wrong, left me for ages on my own, everything was shown to be fine on a scan 4 weeks later though). So am I overreacting? Sorry for the long rant, feeling a bit down and stressed at the moment
