Yeah, everyone is correct.
I havent ever had sex, but i've had some weird cravings the last month or so! It's been buffalo wings, or buffalo chicken sandwitches, or barbeque chickens, or chinese lol.
But thats normal. I'm either getting fat or something is making me grow mirically. O_o'
Anyways, since you had protected sex, there is always a chance you're safe. You havent explained any sickness or throwing up, so that's a good sign. All you can really do is wait until you're period comes because for sure then, you will not be pregnant. And next time, just be cautious, but not too cautious because then something for sure will go wrong, and we don't want that to happen, now do we?
