Hmm that's weird.

Hello everyone, I'm having a strange occurance, lol. I was what seemed to be spotting about 2 weeks ago, then that turned into a full period, lasted about 4-6days. Now, early early this morning, about 3am, I woke up having to pee SO bad, which was weird because I never wake up to pee. And when I went there was a hint of brown. Now I just went pee and there was more brown. I can't be having yet another period?! 2 periods in 3 weeks?! 
Pregnancy could be possible seeing I missed a few pills a few weeks ago.
