Pregnant following D&C ?? Confused

Alexandra

Looking for some advice or others in the same spot. I had a D&C on 12/1 following a missed miscarriage where the heartbeat stopped at 7wks (11/29) nearly six weeks later I still have a very positive pregnancy test and have had some light pink/brown spotting yesterday and today (very light) which seems to have stopped. I got VERY excited thinking this was my period finally coming back but the bleeding has not picked up so now I’m trying to think if this could be implantation bleeding. Would I still have a very positive pregnancy test six weeks after a D&C that was confirmed with an ultrasound was complete? I’m so confused what should I do? I’m not having any pregnancy symptoms at this time either. Thank you!
