Okay so I'm in college and i normally do really good with taking my pill everyday at around the same timw. However on Saturday night i was so tired I fell asleep and slept through my phone alarm that tells me to take my pill! I took it about 9.5 hours late... On Sunday i had alot of brown blood like I had gotten my period. Except it was brown there was no red at all. I'm not due for my period until Saturday. And I've continued to take my pills. Now there is a little red in the blood. But I'm worried because I have a vacation planned in two weeks and i don't want to be bleeding the whole time! Advice? Has this happened to anyone?
