about a month ago, i had my period, and it started to get light, so i had assumed it was ending. my partner and i had unprotected sex in the shower, but barely at all. he had only inserted his penis about 2-3 times but only for a few minutes. he did not ejaculate inside me, but i'm sure still had some fluid on him.

after this had happened, my period WASN'T over, but was irregular/kind of spotted for about 3-4 more days. now my period hasn't come at all this month and i was sure it was supposed to start some time last week. i have barely been cramping at all but i was sick for about 2 weeks & have been feeling more tired than usual. is there any possibility that i could be pregnant?
