I had a miscarraige on 4/5/13 i was 7 wks along my levels that day was 5200 and when i went back on the 9th they were 3000 and that i still had a clot waiting to pass well it passed over that week and i stopped bleeding on the 15th.  Me and my husband have been trying since and about a few days ago i started feeling sick over some smells would want something one min but change my mind a min later I went in to have my lab work done on tuesday 23rd but my doctor was not in and still hasnt called me back. I'm wanting to know could i be pregnant and if so when my hcg levels come back and do say im pregnant because i've taken 4 pregnancy test and each are positive how will i know there not false
