Well I've been ttc, my periods a normal 28 day cycle & 6 days long. I had sex 4 days before ovulating nd the day of my ovulation. Both times he came inside me. I've been getting really bloated to the point that people are commenting about my gaining weight. so far my nipples are sensitive like they hurt when I touch them & I pee a little more. My period was due yesterday, it usually comes to me while I'm asleep so I should have gotten it yesterday morning, I've been cramping but no blood. Could I be pregnant?
