during the last day of my period, my husband and i had unprotected sex where there was penetration for literally one second b/c i was scared. he, however, ejaculated (not in me) and cleaned himself off.. without knowing, his penis was near the vaginal area and we both immediately got scared realizing that he may have not completely cleaned off the sperm. i seriously dont know if there was penetration in the moment. it happened so quickly. is it likely that i could be pregnant? i am not having my period right now and had 2 non-consecutive days of very light spotting. is it too early to get a PT?
