A little over two weeks ago (01/22/2018) my now ex and I engaged in some sexual activity such as oral sex hj, bj and afterwards fingering me. He said that he had nothing on his fingers and that I won't get pregnant but I'm still not sure.But, then I got my period from 02/05/2018-02/07/2018. It seemed normal but slightly shorter. I'm just wondering if there is a possibility if I could still be pregnant?
