Period is not supposed to start for another 12 days. Boyfriend came in me 3 days ago & 2 days ago. No birth control and it was my highest percent chance for pregnancy during my ovulation. it's been 3 days and I know you're not supposed to feel symptoms at all this early! However, i've had really bad cramps that do not feel like my normal period cramps. could this be related to pregnancy? I plan on testing in 13 days if I miss my period, but curious about the cramps! Thank you.
