I got Pregnant while breastfeeding and on the mini pill


I had my first baby 9 months ago. I took a pregnancy test last night because I felt like something has been off lately and sure enough it was positive. I’m breastfeeding and still haven’t had a period yet. So how do the Drs go off that? I know they like to wait 8 was from your last period but that’s been months 🤣 I had incredibly light spotting in November that I thought was my period coming back but it was only enough for one wipe 🤷🏻‍♀️ Now that I’m thinking back on it that could’ve been implantation bleeding 🤔
