I had unprotected sex 6 days ago. Lets say it's been a week. About 3-4 days after the sex I started experiencing on and off cramping, TERRIBLE shooting pain in my upper legs, increased appetite, nausea, headaches, and very tender boobs. My body just feels so off. I know something is up with it. Please tell me if this can happen this quickly. Oh yeah my scent is very sensitive too.

When you had sex, is it your fertile days?

Do you notice any change in your discharge?

It would be too early to have pregnancy symptoms. Wait until you miss a period and then take a test.
