Hello, so I've been having unprotected sex a lot this month. My boyfriend's not very big on birth control or anything. But beings he keeps "forgetting to pull out" he said to take the pills.

Anyway, my thing is that I have no period symptoms. I dont think. I'm supposed to start in 3 days. I've been a little nauseous for a week with a couple headaches and hungry. Like craving odd stuff. But... the thing is. We didnt start birth control until Sunday....

Do these sound like period symptoms or pregnancy?
