Hello! I stupidly had unprotected sex during the 4th day (Jan 25th) of my period (I typically have 5 day periods which the first three days are bright red bleeding then the last two days are just very light and brown) and just to be safe I took Plan B literally 24.5 hours later. I typically have 30 day cycle +/- a few days. Five days after taking Plan B (Jan 30th), I'm experiencing pinkish/brownish mucus discharge. I know that it's a common side effect to the medication but do you feel that I am currently started a second period now? Do you think I should worry about being pregnant? I am in college right now and can not afford a child.
