Another PIL one

[smu06set]

Back story - I'm pregnant, 18 weeks. I've had horrendous anxiety this pregnancy, really terrified that there is something wrong. Never had this with DD, so can't shake the thought it's some sort of premonition. As a result our immediate family know, but we asked them up front not to tell anyone else until we had the 20 week scan. They are well aware of my anxiety and understand it too (MIL went through a late loss).
Christmas eve we go to PIL and DH wants to go to the pub with his dad. Fine, I offer to drop them down there as it's raining. We collect FILs friend on the way. This friend gets in the car and the first thing he says is "Congratulations you two!". FIL is silent and the friend follows up with "it wasn't a secret was it?". Cue awkward silence then thankfully we are at the pub and they all get out.
I then have to spend the next 3 hours with MIL before collecting them from the pub, then I can escape. Those 3 hours killed me. I was in tears once FIL and DH left the car, pulled myself together (ish) for MIL and fell apart once I got home.
It transpired FIL got drunk and told 4 of his friends. One of which has only ever been horrible to me.
Not once has FIL apologised or even mentioned it. Only once we got home and I had a good cry on DH, and DH messaged his dad did he even acknowledge it. I've had no contact from them since, no apology, nothing.
I know most people will say I'm being silly not wanting people to know, but I'm genuinely that worried about there being a problem at the 20 week scan.
It's not so much that FIL slipped up and mentioned it, I get people are human and make mistakes. It's that he tried to hide it. And when the secret was out, he didn't apologise. It's like he won't admit he was wrong.
AIBU to cut contact? At least until after my scan? The whole thing has ruined Christmas for us now and I can't face them...

Really helpful telling someone who is suffering with 'horrendous anxiety' to get a grip

Sorry but yes you are being unreasonable. It's a bit OTT.

You were in tears and have fallen apart? And want to cut contact? Because your FIL told his mates you're pregnant?

^This is not normal behaviour.

You must have a bit of a bump by now surely. And would you honestly not tell anyone if you went through a late loss anyway? As someone who has had miscarriages myself I found it much harder talking to people that hadn’t known I had been pregnant in the first place than those who knew I was pregnant.
I would give your in laws a break they are just excited for you.
Also I would just like to add that the first scan picks up the majority of abnormalities these days and almost all major abnormalities. Please try and enjoy this pregnancy xxx

No it’s not “normal” behaviour but it is anxiety related behaviour

It's only a couple of weeks until your scan. It won't do any harm to avoid them until then.

Have you talked to anyone about how you feel? Hopefullly your scan will put your mind at rest but if these feelings persist you should discuss them with your GP/midwife.
