My fiance and I had unprotected sex the day after my period ended. He didn't pull out in time, the tip was still somewhat in my vagina. I felt the cum down there and on my leg. Previously before my period, Nov 21st through 27th my patch fell off and I had to apply the only one I had left which wasn't suppose to be reapplied till Nov 29th. I got my period thur Dec 3rd, normal use of patches I get my periods on Wed. But I got it Thursday and it ended Sun. Need to know if I could be pregnant
