Hey,there.Have you lost a great deal of weight?Are you stressed out?Do you exercise excessively?Any or all of these can cause your period to skip.Sometimes ,your hormones get out of balance and you may need some type of medication to restart them.You really should see your doctor to get a thorough check-up.You need to get your thyroid checked out as well,an imbalance in your thyroid can throw your period off as well.Don't delay!Good luck to you.Patty

Also u could still be preg and get a neg urine test. My guess is that ur not though, cuz u'd prob have symptoms by 4 months. Good luck

Stress? I have had times where I didn't have a period for three months and it was stress related. Also it could be that you might be some sort of sick. I really think after four months you should go see a doctor despite what anyone says on here. We can only guess...I hope everything is alright. Keep us posted and good luck.

i dont think there is anything you can do. I once didnt have my period for like 8 months and just got more worried because of it. It turned out I had a pitutary tumor ( which is not harmful) but it was somthing and now im on meds and everythings ok. Id go to the doctor as soon as possible

Thanks for your input, I appreciate it. I'm so glad I found this website and people who are thoughtful and sensitive. yay for you!!

wow... i have this same problem... i was on the depo birth control shot for 3 years, i have my period EVERY day for those 3 years. my last shot was in june 2008. i havent had a period since august n its almost march now. i went to the doctor repeatedly when i was having my period for 3 years n they couldnt figure out why tht was happening to me. and now ive gone repeatedly for missing my period for almost 8 months now, not stressed, eating healthy, i definatley dont excercise a lot, and i am definately not preg... so if yu figure out whts goin on could yu please let me kno, lol i know this is your question but yea. thanks
