HCG advice

St

Hello everyone … I’m new here …. I have pcos , my husband and I found out on Sunday that we are pregnant, I went to my primary care doctor Tuesday to get it confirmed. I also have had bleeding go on for 4 weeks now mild cramping started Monday , I went to the ER to get checked out to be sure everything was fine, my levels there were 380, I went to my OB to get my levels drawn yesterday and it dropped to 203, this morning I took a test , and that is the very last one that is not dated. Any advice did this happened to anyone else but they had a successful pregnancy?
