I Sunday started my birth control three days after I ended my period. I'm on my 6th day of loestrin and my fiancé and I had unprotected sex today. He didn't go in me and wiped off with a towel after but we kept going a few minutes later and he rubbed the tip against my vagina and put it in me. I'm on the 15th day of my cycle and my cycle is usually 28 days. What are the odds that I'm pregnant?
