My doctor is not following my hcg levels post m/c- she's actually out on maternity leave and I won't see her for another two weeks. Anyway, I think I'm getting ready to ovulate and was wondering if that means my hcg is back to 0. Should I take a hpt to see if the hcg is gone or does it really matter? I've never used opk's before but I'm going to go get some this evening. TIA for any insight.
