I m 16. Ive Been In A Relationship With My Boyfriend for 3 years. I cheated on him Jan. 1st, 2014. My last Period was Jan. 11th, 2014. Me and my boyfriend had sex almost everyday after that. I went to the doctor March 21st, 2014 and they told me I was 9weeks6days pregnant. My due date is October 18th, 2014. is there anyway I could have gotten pregnant from intercourse on Jan. 1st, 2014?
