I know I'm highly stressing over this. Paranoia. Im 16 and had sex for the first time, and yes, it was protective. I feels so stupid because of it. It was a couple nights ago since it happened and started worrying yesterday, going around asking my friends for advice to see what was the affects after protected sex. I don't feel that hungry as usual. Slight pains here there and the uterus. Slight burning urine. I have irregular periods ever since I started them at the age of 10 and that highly scares me. I looked everywhere to see what everyone elses symptoms or affects were afyer there first time protected and cannot get a straight answer that seems to scare me highly. Again, I know I'm paranoid and stressing over it, I just want some answers. Help?
