Pregnancy test…almost 7 week postpartum

Jess

So hubby and I did the deed unprotected at 5 weeks 5 days postpartum. I freaked out and took the morning after pill the following day and out of curiosity took a few pregnancy tests today at 6 weeks 4 day’s postpartum and got faint lines on 2 out of 3 tests.

I have bottle fed my son since birth and also started taking my regular daily pill a week before having unprotected sex. Has anyone ever gotten pregnant this quickly after giving birth? Thinking it could be left over hcg
