So the very day after my ovulation I starting getting cramps till the day of my period my period only stay for three days but this one doesn’t seem like it wants to go up and I’m still having cramps and backs ackes but they never stay this long they only stay for the first day of my period but these don’t want go away 🤦🏽‍♀️. I’m so confused me and boyfriend still had sex on my ovulation day I took a test to make sure I was ovulating and I had a peak so I don’t know but Eva since that I been feeling different and sick and really lazy and tired 🤦🏽‍♀️ I’m so confused I know u can’t have a period during pregnancy but my mom said she did her whole 9 months so I don’t know 😴
