After sex for like 5 days my bodys feel weird, and I feel like throwing up, and having cramps on my bottom belly .What does this sign feeling mean?

I means that you should be visiting your doctor. To find out why.

Okay, but this is unprotected sex its not a sign that I might not get pregnant right?

The only sign you might be pregnant is when you are late several weeks for the next period.

These other things will be symptoms of something else. And why I suggested the doctor. Might just be a virus or something you ate...

It takes the sperm about 3 days to reach egg, so there is no signs the first week or two.

Perhaps you caught some cold or flu from the guy
