can i be prego?

Rebecxa

I usually ovulate right before period, it leading to my period. I had unprotected sex twice first day of my period. (I know i was ovulating the day before) 3 days later and my period just stops. (my cycle is usually 5-7 days never shorter) could it possibly be that i am pregnant that made my period stop?

Ps. i have been throwing up the passes 2 nights leading to morning but feel fine later that day!
