PZ, Pregnancy after loss or ltttc is sooo hard and scary. I dont think I really have any answers for you but try and keep busy, like super busy. Perhaps you can ask for a scan at a private clinic it might cost a bit but if it eases your mind then so be it, we had scans every few weeks in the first trimester to keep me sane and I had bloods every 3 days from 3.5 weeks- 8 weeks. I also POAS regularly until about 36 weeks All your pregnancy signs are great and take them as a little bit of reassurance but I know that doesnt make it any easier. The fact that you have seen that little one on scan with a strong heartbeat is a great start too. Hang in there babe
