Well I know that the most fertile time for a woman to get pregnant is right after having a baby for some reason but thats what my professor says. The brown spotting does sound like implantation bleeding but it could be from having sex so soon after the baby, I would wait and see if you get your period if not I would go see a doctor instead of taking a hpt to be for sure.

Ditto what the others said. Also you had your baby about a month ago, you wouldn't have gotten your period yet and if you are breastfeeding it will be even longer, I did not get my first period till my son was like 2 1/2 months old and that was cause I finally went on the pill.

I remember after my children, scant brown bleeding after I thought bleeding had stopped, but it was just the left over bleed from the birth.

yes with what everyone else says. You really dont get your period back for a while. My son bout to me 4months and I just got mine last month. So I hope that you ok. B/c I though I was pergo too but I got my period so I was ok... Hope you that best of luck!!

I disagree- I got my first after baby period a month to the day after the birth- 28 days exactly. I was breastfeeding. I also had sex as soon as I finished bleding, but we used a condom because you can be very fertile right after birth.

Ask your doctor at your 6 week check-up. He would be able to do a test or something- my aunty found out she was pregnant with her 2nd at her 6 week check after her first, and then sound out she was pregnant with her third, at the 6 week check after her 2nd !!!!!
Her 3 girls are very close, it wouldn't be the end of the world to be pregnant so soon.
Good luck either way!
