Is this my period ?

On 8/9 I had a d&c; for a missed miscarriage. I should of been 11 weeks. I basically miscarried at 8 weeks. So on 8/29 I got a blood test my level was at 76, on 8/31 I was at 45. That's a big drop in 48 hours. So I'm assuming I wouldn't went to 0 within the next 2-3 days. So on 9/7 my level was at 15. I had sex this morning and when I peed after the cum and discharge that came out was bloody. And when I pee a few drops of blood come out. But I don't need a pad or tampon cause its not just coming out. Is this my period ? Shouldn't I have ovulated first before my period. I still had hcg in me 3 days ago. I've been having sex almost every day since surgery trying to get pregnant before my period came. I hope this isn't it.
