I had my baby 5 weeks ago. I had sex at 2 weeks 4 days pp. Unprotected and he came inside me. We have done the same thing several times in the past few weeks. I know postpartum is a very fertile time. I nursed for a few days and pumped for the first three weeks. I haven't had my first pp period yet and have no idea when to expect it. If I took a pregnancy test now, would I still be testing positive from the last pregnancy? When should I begin to suspect pregnancy?
