I have been having cramps and I have been really hungry and nauseas latley... itl be one week on Friday after having unprotected sex... I been having headaches and I'm really concerend when I try to eat I get even more nauseas I need some answers please

What answers can you possibly be wanting to hear?
Pregnant, not pregnant, maybe pregnant.
The answer is the same for every woman between puberty and menopause: maybe. Even women using birth control: maybe.
I take it that you didn't use BC just that once? Many a pregnancy occurs just that once, sorry.

Id like to know if these are a normal just after a week... sorry I wasn't clear

I just wanted to know if this is normal after a week sorry I wasn't clear

There's so many shades of normal, it's better to say is it common - yes it's fairly common to feel those effects as soon as you say, but it could also be an early period, or a stomach virus, it's just too difficult to say. We don't even know when your next period is due, what BC you were using, your age, and so on - do you see how impossible it is?

Um OK... my next period is due on the 19 I'm 19 and I'm not using any BC... thanks for the help
