Just want some input

So on October 2 I had a complete miscarriage. I say that because I have had one before and know what look for. I bleed from sept 27-oct8. That was it, no more pain or cramping at all. Then starting oct 22 and continuing through today I continue to have only right side pelvic pain (like when ovulating). I had sex on oct 23 and oct 30 (unprotected). So yes I know there is a chance of pregnancy again. My main concern is that not all the product was passed. I’m going to get labs done to see what my hcg is. Just wanted to hear other stories too. Thanks in advance.
