Recurrent miscarriage testing

Jenna • Mom of 1🌈👶🏻 ttc #2🤞🏼 lucky number 3 again? 0 for 2 this time around

Anyone have testing for recurrent miscarriages and pinpoint a cause? 0 for 2 right now trying to conceive baby number two and with our first babe he was our third pregnancy. It’s so stinky but my doctor has been reassuring that pregnancy loss is so common and that there’s no need for testing. I got blood drawn last time for them to check levels and things came back normal. Prior to ttc I had some atypical cells removed from my uterus, I wonder if that could affect it but he seemed to think it wouldn’t. Anyways, just wondering if anyone has had experience w testing to try and find out a cause and it is even worth it. Im disappointed but still ready to keep ttc. We got a healthy pregnancy last time and am hoping for the same. Anyone else in the same boat?
