Pregnancy/Health Scare - Fiancee - Help

[ZBTHorton]

Ok.

So about 3 days ago my fiancee had this horrible spout of stomach sickness and headaches worse than she's ever had. She couldn't even talk to me they were so bad. We were at the Cowboys game, and she sat silently the whole way home and threw up three times. Then went to bed with the same massive headache she had before she got sick.

Everything was fine for two days, and now today she is cramping again. Feels like crap. Head hurts. Etc.

Here are necessary details:

#1. She's on birth control.
#2. Her last period ran from October 16th-22nd.
#3. She is kind of paranoid about getting pregnant, and assumes any kind of sickness is always that. Normally I TOTALLY brush it off, but this time she seems really sick.
#4. I've never seen her get sick like this.
#5. From what I can remember, we've only had sex twice in the two weeks since her period. October 22nd and Halloween night.

I'm looking for some medical advice here. I've looked through the net, and can't find anyway that she could be pregnant when factoring in Ovulation days, etc, unless it's just a miraculous conception.

I'd appreciate any advice from people who have gone through this, or might have some experience in the field. But if you find something REALLY worth while on the net post it here. I'm pushing the envelope here, because she can't take a EPT test until 4 days before her period, which doesn't happen for two weeks...so this is really beginning to stress me(us) out.

Thanks.

EDIT: We don't use condoms, but I never 'go' inside of her.
