Hi I've had 3 chemical pregnancies back to back on 3 consecutive cycles.. Implantation happens I get all symptoms and slight positive pregnancy test for few days and then I start bleeding before 5w 3d, which was the maximum it ever got to.. I was on progesterone suppositories for the last one.. What are my next steps.. Pls advice I was able to collect tissue on last loss, But didn't test, havent started bleeding yet on this one, if I manage to get tissue should I check for chromosomal abnormalities?
