I has sex for the first time on Feb 25th around midnight. This was 2 days after my period ended. The condom broke but my boyfriend didn't ejaculate at all. On March 1 at 8am I took plan b as a precaution. I went on antibiotics on March 6-17 because I had an abscess. My roommate is on birth control and is going to get her period on March 21. She has changed mine before. Right now I have clear drainage and bloating. I'm not tender, have nausea, or spotting. Am I freaking out for nothing? Is my period just going to be late?
