I had sex about the second or third day of my period and my boyfriend released in me. I didn't think that I could be pregnant but,now I wonder because yesterday I had a really bad case of flu like stuff, I was feeling very nausous I vomited a couple of times and I couldn't move. My body was hurting and I was cold now I feel okay, a little queezy but, not like yesterday. Is morning sickness really that bad or did I just have the flu. My sister told me that she felt sick too but, not as bad as I did.
What do you think it was.
