Ovulating 3 months PP while breastfeeding?!

Amanda

So I’m probably going to sound very dumb. I just had my second baby 3 months ago and I’m not on any birth control as with my first I never got a period or ovulated for 11 months. I exclusively breastfeed and I’m so confused as to what’s going on?!? My uterus started hurting the other night and I took an ovulation test the next morning and it was super positive… problem is I had sex Wednesday night 🤦🏼‍♀️ am I totally screwed at this point?!?
