Grey congratulations! My only advice would be to try not to think about it. Avoid excessive googling. This time round, I didn’t tell anyone, didn’t start getting out maternity clothes (despite v v early flab), didn’t even register with GP/midwife. That was my decision btw, I’m not recommending it to anyone else. I did download the pregnancy app. If I’m lucky enough to conceive again I don’t think I’ll do even that because it is so sad to think the baby had passed away weeks before I realised.
I booked a scan at 8 weeks because I know that if you see a HB then your odds of successful pregnancy are v high. As it turned out there was no HB and I started to miscarry that day, but knowing I had the scan coming helped me to cope with the earlier stages.
Sore boobs aren’t necessarily anything. I get them sometimes with PMT and haven’t always had them in pregnancy.
Try to look after yourself and keep busy and healthy... easier said than done I know. All the best.
