It is too early for any pregnancy symptoms. Your first pregnancy symptom is most likely a missed period. Continue taking your birth control and ALWAYS use a back up method (condoms are a good choice) when you are taking antibiotics. You knew this, yet didn't do it.

Relax. Your nausea is not a pregnancy symptom.

Me and my girlfriend had sex 6 days ago now. It was her first time. We didn't get to go for long before she had to leave... So we went without a condom. I came no where near close to ejaculation, but still, she's been complaining of nausea/vomiting, headaches, bad cramps, and dehydration since 2 days after we had sex. Last month she had an irregular period though, much longer than usual she said, went from 3-4 days to a week. So she believes the fact she lost her virginity and the fact she had an irregular period had a big role in this. Is it likely she is pregnant?

idk when the symptoms are meant to come about, im still waiting to see whether i am or not.

Wayyyy too early for those pregnancy symptoms. Sounds like she is really anxious and causing herself to feel pregnant. It takes at 10-14 days before your body start producing enough hormones to be picked up on pregnancy tests. The same hormones that the pregnancy test recognizes are the same hormones that cause pregnancy symptoms.

Her FIRST symptom will likely be a missed period.
