My last period was Oct. 24. I'm sort of irregular-ish. My next period would've been the week of Nov. 24-Dec 1 (it can vary within that timeframe). I became sexually active Nov. 1. My boyfriend and I have used a condom most of the time, but not always. I took a Plan B pill Nov 18 because we were scared he didn't pull out in time.
I did not get my period within the week timeframe, but started to bleed Dec 4. It's slightly brown but is becoming more bright red (it's not just like 4 drops, but enough to have a light pad on for now), and about 2 days leading up to my bleeding I was getting severe cramps, like I would if I were to get my period. This has happened for a day now. I also have had periods where I have had brown/bright red bleeding light enough to use and change a pad every other day.
If my severe cramps continue, as well as the bleeding for more than say 4 days, is this implentation bleeding, my period, or side effects of Plan B? I took a pregnancy test Dec 1 and it was negative, so when the bleeding stops should I take another one?
^ Also, we have had regular sex about every other day since Nov 1; we did't use a condom until around the 13th-15th of Nov, but he has always pulled out, but anything could happen I know. That's why I'm not references any specific dates on when we have had sex. We have used condoms since then however.
