New to the app! I’m having some anxiety! My boyfriend and I were having fun. (We did NOT have sex! ) but he did finger me! He says he didn’t have anything on his hands and is typically very careful. He did cum however it was into a condom while i was giving him oral. And the condom didn’t break! However I’m unsure if there was something like precum on his hands... I’m 3 days late but I have been stressing. And I feel a tingle like my period is coming which is normal for me. Plus I’ve taken 3 tests since the day my period was due and they were all negative. Am I just worrying to much? Or is there a chance I’m pregnant?
