girls on the pill: does this happen to you?

Mary • 22
I am currently taking a low estrogen pill. I missed it by three hours on Sunday because I had a bad cold and fell asleep at like 5 pm lol. I jolted myself awake and took it asap but was still three hours late. I love how the pill has cleared up my acne and how i have no negative affects. BUT when I miss a pill, I have a FULL BLOWN PERIOD- and I don't mean like miss two days and start a new pack miss it. I mean like take it three hours late one day and then get a 7-day period with cramps and tons of blood. Do I need to take a pill with more estrogen?? Or restart taking the pill with my old pre-bc cycle? Like why does this happen it's hell. I am so precise about my pill but sometimes life happens and you're gonna take it late.
