Hello.Almost a month ago I was giving my boyfriend a ha****b.The tips of two of three of my fingers got a little bit wet(he was wearing his boxers and jeans).I washed my hands 3 times woth cold water and soap,after 2 hours I fingerd myself with the same hand.My period is a few days late and I am really worried.I never had a regular menstrual cycle.Could I be pregnant?
