Pregnant??.....

Alex • I'm 17 & taken to my amazing boyfriend kaleb 💞
My boyfriend and I had unprotected sex on Wednesday night &Thursday morning, we are not to sure if he pulled out on time or not & I'm starting to get really bad cramps ( I don't get any symptoms before my period) I have also been getting quite moody, I'm scared that I'm pregnant? Do you think I am??.....
