Me and my bf had sex 2 days after my last period which began on November 29 and ended December 2 of last year. We have had sex numerous times since then. When the end of December came and no period,I got worried. January came and still no period until the 15th. I did have some stomach cramps that started when I started to bleed but the next day the cramping stopped but I'm still bleeding. Also I'm having flu like symptoms and feeling extremely tired. I do have craving and use the restroom more than usual. Can I be pregnant?
