Pregnant

Has this ever happened to anyone??

I had sex 5-7 days before my period was due. Around 12am. The next day around 11am. I started bleeding. Which I didn’t think was my period because I ALWAYS cramp the day before my period and severely during and I did not have one single cramp. Well the bleeding was the normal amount and normal time of my period but 0 cramps at all. Now, 9 days after sex, I’m having like weird symptoms. Has anyone had something similar happen and actually been pregnant????

I’m not asking if I am personally pregnant or not. I’m asking if anyone has had this happen.
