Question...

So I feel like I ask almost the same question over and over but in different ways. I feel like I even annoy myself for asking y’all, so I had my Mc almost 5 weeks ago and had my follow up about 2 weeks ago. Doctor said I had some retained tissue but not a lot said about a week should be enough to get it all out, my hcg levels were 166 and I’m assuming they have dropped even more since pregnancy tests are negative now. I haven’t started my period and keep spotting with the occasional like what you would see right before your period really starts like a little heavier than spotting but not enough for a tampon or even a panty liner. So my midwife said to let them know in 4 weeks, which is now down to 2 weeks to let them know if I get a positive or negative on a test for a possible new pregnancy. My question is since I’m still spotting from my Mc could I still get pregnant? Cause I haven’t had a real period yet since my Mc so I’m confused. I can’t tell if I’ve ovulated because tests show positive every day still but pregnancy tests are negative..I have a feeling I’m still retaining tissue that’s why I’m still bleeding but I’m just curious if I can get pregnant again. If you’ve been in this situation or you know how to tell if you’ve ovulated while still spotting from a Mc I need some help lol
