Am I pregnant?

Is four days uncommon? How long does your period normally last? It can be as short as three (like me) or as long as seven. If four is normal to you, then there's no reason to worry about that. Also, if you needed a pad or tampon it's likely it really was a period and you didn't mistake implantation bleeding (a little bit of bleeding after a baby is fertilized) for a period. If you got your period on the seventeenth and it lasted four days that means you got off it on the twenty-first. Now it is the twenty-fifth. It's almost impossible to get pregnant right after your period, even if you aren't using any form of birth control, because you can't get pregnant if there's no egg to fertilize. Assuming you have an average 28-day cycle (not all women do!) you would ovulate around the start of each month (this is a guesstimate). So if you have sex then the chances are much higher that you could get pregnant. Anyway, if you had sex directly after your period, I don't think you're pregnant. If you meant you had it before your period, like I said, that depends on WHEN you did it.

I would recommend "Fertility Friend," a very useful app for this sort of thing. It's useful for people who are trying to get pregnant AND for people who are not (I use it for the latter). You just put down when you have your period and when you have sex, and it tells you when you'll get it next, when to ovulate, and when or when not to have sex. Super easy!

Really ?

It's possible, it's not likely given the timing and that you are on birth control.

Those pills aren't breath mints. They keep you from getting pregnant.

I'll just consult my crystal ball

Who knows? Who cares but you? Quite obviously if you are prepared to have unprotected sex, there is always the present risk that you are, or will become pregnant. So please don't waste our time here wondering. If you aren't pregnant this time, you will be next time, or the time after.

Take a pregnancy test. Cramps don't start that early. The baby if you are pregnant isn't even the size of a pea yet. Since you're still so young if you aren't pregnant I highly suggest talking to your parents and doctor about birth control.
