Uht oh...

Shelby • I`m the mother of 2 amazing toddlers, both boys. (1yr & 3yrs). pregnant with #3 and this one is a girl <3

Does anyone know? How soon after having a baby, can you get pregnant again? I just had my son early November, and Im not breastfeeding. We've been having sex since 3 weeks after delivery, no protection. I thought I started my period this morning but it stopped...and now im starting to freak out thinking it was implantation bleeding and #3 is on its way...

Any one care to offer some peace of mind?
