Pregnancy Info HOME

So my fiancee and I both want children but at first we thought that we wouldn't be able to because he had a hard time as a teenager and did alot of drugs, so he thought he was sterile. Because of this we've been having unprotected s_x and he has left his sperm inside of me several times over the past year. Well, 2 weeks ago, two or three days after the last time we had s_x, I coughed and a small amount of blood came out. This was right after or during ovulation. Since then I've been tired, i've been burping more than usual, I can smell EVERYTHING, and I'm almost done smoking cigarettes because the smell of an ashtray and cigarette smoke makes me want to vomit. The smell of my puppy's dog treats makes my stomach turn. I haven't thrown up but have come close to it. Now, I believe it's been 31 days since the start of my last period (May 6, 2012). I've taken two EBT pregnancy tests (Saturday June 2, Sunday June 3) and both were negative. Any ideas? Do you think I'm pregnant? I keep thinking that if I'm not my fiancee will be disappointed because he didn't think he could have a kid.
