In July I got my period on the 12th. Aug. I got it on the 13th. Sep. I got it on the 16 and now oct it was early three day. Every time it starts heavy n I have really bad cramps where I can barley move for the first half a day then it'll get light and down to almost nothing for a day or two then be really heavy for the last day or so. What is wrong? Could I be pregnant? Me and my boyfriend use the pull out method and have for the 7 months we been together my friend got pregnant this way is it happening to me?

It's not likely due to pregnancy, although pregnancy will be a possibility sooner or later. This is due to the withdrawal method, although widely used, not being the most effective method for many couples. See what happens next month... if no period, try a test.

Your cycles are not off by much from month to month, not enough to be considered irregular, and the duration/flow may just be the norm for you. Some women do experience extreme discomfort at some point during their period.

If your periods haven't changed from what they usually are, it likely is what your periods are like. This may change as you get older and/or after you have any children. Sometimes the use of certain types of birth control can be helpful in relieving the discomforts as well.

If this is not the norm for you, best to speak to your doctor about it. It would be worth the peace of mind for you.

Since pull out is not a real method that works, you will get pregnant sooner or latter having unprotected sex.
There is plenty of sperm in all the early fluids, not to count the times he is a little "late" in pulling out.

But since you are having periods, it can be many things else, from other STD issues, to infections. You need to visit your doctor for a check up

No I don't think you are pregnant, you have had a period every month, even though it has been a little late or early, it has still arrived.

You do need to sort out some other form of birth control.Sooner or later you will conceive by the rhythm method.I think the birth pill would be ideal for you, it will regulate your periods.also ease other symptoms as well.However, this is your choice to be made with your doctors advice

I would go see your doctor who can also discuss other methods of birth control, that you may be more suited to.
