Hello Anonymous,

Why did you start taking birth control pills on December 26 and stop three days later on December 29?

When you say " another cycle" do you mean that you started your period?

If you had your period from January 1 to January 5, you calculate your next menstrual cycle by counting from the first day of one period (January 1) and how many days your cycle normally is. This should give you the start date of your period for February.

Does this answer your question?

I end up going on a vacation and realized I left my pills at home I thought I had them in my purse but I guess not...I did have another period on the 1st of January and that was 2 days after I stop taking the pill which was on the 29th the day I left on my trip and no I didn't continue to take them because I thought I messed up and wanted to start over when my next period come but I dnt knw which 1 to go off of. If I go off the 1 in Dec I'm late with my period but if I'm suppose to go by January then I have until the 29th...being that I did have sex unprotected 3 times and I been having cramps like I'm going to start my period for 3 weeks now and I been urinating frequently and boobs are not all that tender but they do tingle a little.
