Have you had any sex? That would be kinda important for ruling out pregnancy...

It sounds like you body is having a bad time readjusting to it's own schedule.

I'm not pregnant i've taken multiple tests.

Well, if you're confident you're not pregnant, then i'll give you this:

when I first got my period, I was about 13. All went normal, it was just like any other period. Then, I didn't have another one for 6 months!! I don't weigh a whole lot, so that's probably part of it.

I'm going to have to go with the original thing I said: it sounds like your body is having a very had time getting back onto a natural schedule. It may have gotten so sued to the pills that it can't control your cycle or start it up correctly.

Hang in there is what I can tell you. I just got off of my pill after being on it for ten years! It's only been a month and i've had some crazy symtpoms like the hair falling out and my face breaking out. I did get my period - just a week off from when I should've gotten it on my pill. You have to remeber that your pill suppressed your ovulation cycles and basically masked your system so my best advice to you is go back to your doctor if you're still having problems and also get yourself on a good multivitamin and get plently of calcium/magnesium. I also think you should look into an herb called vitex, also known as chasteberry tree. Vitex is supposed to work with the pituarity gland and work with your hormones, though vitex is not a hormone in itself- check it out on the internet-i will warn you it is a slow acting herb and may take 3-6 months to balance it all out. I just started taking it myself just so I can get my natural cycle back in swing- good luck!

I too didn't have a period for 4 months after quitting my birth control pill!! It was terrible, and I took a pregnancy test and it was negative. I just started my period last week. I went and got back on a different kind of bc though so it could help with it. Hope things get back to normal for you, I know how stressful it can be!!
