I last had my period on February 19th, it lasted for about 5 or 6 days... I had dry sex on March 3rd. Was I ovulating at this time? And could I be pregnant? I was wearing tights with thin underwear underneath, and my boyfriend was wearing jeans with boxers underneath. I think he had a little bit of pre-cum but I don't know if it got through or not. Today is March 19th and I'm usually early for my period, but I haven't got it yet... I'm really worried, if someone could help me out I would be very greatful.
