So my last period was January 9-13....on the second and and third day of my period my boyfriend and I had dry sex. He got precum in my undies...but i had a huge pad on. He didn't have underwear on, but I had on panties and a relatively thick pad. I usually have pretty normal periods as far as I am aware. I think I'm due tomorrow for my period but I don't feel like I am going to start..I just feel very scared. I've been emotional and irritable. I've had some cramping but I'm also constipated...so I don't know. Do you think I am pregnant? Like from what I have described?
