I had protected sex (condom, no complications, no rips or leakage) on Monday (today is Saturday) and I'm wondering if possible pregnancy signs could come this soon? My period isn't for about a week or 2, and I'm feeling constipated, very hungry, my stomach hurts when you poke it, and yesterday I had a bit of cramping. At first, I didn't worry because we had been very safe, but then I thought about it a lot on Wednesday and have been extremely paranoid since Thursday. I'm also moving soon and for awhile that made me very nervous, but now I'm just worrying about the possibility I could be pregnant! This is my first time having sex in a long time, and I'm pretty sure I was safe with the condom. I am going to go on birth control next time, but I won't see my boyfriend for awhile, so there's no need to right now. I was sure we were safe but now I'm terrified. Help!
