Since you had menses 2 months ago and never again since, it’s quite hard to predict your fertility, but it’s certainly possible to get pregnant even while breastfeeding. Perhaps for now, take folic acid just in case, and repeat your pregnancy test every week for the next few weeks? If it’s still negative for 3-4 weeks, then you’re probably not pregnant from that episode of intercourse
Thr is a chance of pregnancy for u cos ur period is back alr. Y not for a blood test? Most accurate..
