I had sex and my partner used a condom then I got freaked out and I ran to wallgreens to buy an emergency pill after 33 hrs I had sex. Then a week later I got my period but the color was different and sometimes it stopped at night, but I had it for almost 5 days. Also, I noticed that my nipple is more tender and right now because I am freaking out I noticed that I go pee more often (or maybe because I drank a lot of coffee)
