Help please...

Hey y'all.

I had a mmc in December. I was 9 weeks pregnant, and the baby had stopped growing at 6 weeks. So I had a d&e on Dec 22nd. . and had sex 5 days later. ( I wasn't bleeding, and had no pain.) & I still haven't gotten my period. I guess my question is.. Is it possible to be pregnant right now? I didn't think it was possible to conceive if you hadn't had a period first, ya know.. To ovulate.. But I've never had a d & e before so Idk how this works.. Any help or advice would be amazing ! Thank you, & God bless and baby dust to all.
