Recent miscarriage and D&C

De

At the end of April I started to miscarry. On May 1st I had a D&C...it was one of the hardest things I feel I’ve gone through. I felt like my body failed and all in that I was on birth control. The IUD. It expelled out but unsure when tbh. Well, when I miscarried I didnt heavy bleed. And it was even lighter after the D&C. My bf and I had sex a week after the D&C....and had had unprotected sex 3 times since then. As of yesterday I started spotting but idk if it’s my period or spotting cause I could be pregnant. The doctor said it’s possible to get pregnant immediately after because I wasn’t far along.

I’m almost scared that if I am my body will fail again. I don’t even know if I’ve ovulated either.
