Here's the catch. I am not planning on getting pregnant.My period, came in yesterday(Sept 2nd) and it was a regular flow, no pink or brown spotting and such, but then comes today and it slowed down a bit to much (Sept 3)(It's like any regular period, red!)My period was 3 weeks late! and that is very abnormal for me. I took a test and it came out negative but I'm still worried. I'm not so sure what to do, and there isn't an answer to this problem.I took plan B about 7 months ago, could that still affect my cycle until now? At some points, my period has been late for a week, or almost 2. (My cycle goes around 34-36 days, somewhat) after taking the pill.I honestly can't get this issue out of my head. Any advice?
