I am three weeks post medical abortion and I am still getting what I feel are very strong positive testing lines...I took these about a half hour ago.

I did just start bleeding again after a week of no bleeding and it’s dark red, does not appear that it could be implantation bleeding. Could this be my period? My husband is afraid to have me go back on birth control pills because I have PCOS and he’s afraid we won’t get a positive result as soon as we did the first time (even though we were shocked and were not expecting it). Currently we are using condoms which I don’t trust, but it’s all we can really use that doesn’t cause any side effects. What do you guys think? Is it normal to have lines like these three weeks later? Thank you for your input.
