Okay, so I had sex the night of October 3. It wasn't but for three minutes if that. He used a condom, and didn't . I bled for three or so days afterwards. Then started My period a few days after. I'm scared I might be pregnant. I should be starting my period soon. I took a test yesterday, and it said negative, but 3 weeks is too early to know. I'm cramping, my back hurts, and my breasts are sore. I don't know if I'm just paranoid or I'm actually feeling pressure when I press down on my stomach. I feel a little bloated. Could I be pregnant?

Bear in mind that PMS and early pregnancy are very similar and often confused.
You are now on a waiting game for your next cycle, if you pass this date by several days then a repeat HPT with first morning urine would be helpful.

Thank you!

Have you had sex since your last period?
