I had my period on 1 may 2015 and had unprotected sex just after my period,, having a tingling sensation in my uterus, am i pregnant?

Pregnancy test done?: Unless you've performed a pregnancy test which should be done NO SOONER than the 1st day of your MISSED PERIOD then, there's no way to know. Tingling sensations and all of the other symptoms you've heard (or had even if you've been pregnant before) cannot diagnose pregnancy. I always recommend that patients wait for 1 week longer than their missed date simply because they could be late.
