I've been taking birth control for more than a year now I get my period every month for about 6 days I got it this December and after I got my period I kept on taking my bc I missed my pill for 3 days before my ovulation and had sexual intercourse and my husband came inside me two days later I started spotting like a rustic brown color and this kept on for 6 days after the six days I started heavy cramping but haven't gotten my period and I'm always regular so what's going on? Can I be pregnant?
