I'm 21. Had my son a year ago. My periods were regular always have. Was on birth control. Then my periods just stopped its almost five months. Tooken atleaste ten pregnancy test even a blood test all came back negative . What is wrong with me.

Did your doctor give you an sort of explanation? Was any further testing discussed? I would set another appointment to go in an discuss it.

I second Doula's post. This really needs to be seen to by a doctor. We can guess, but guesses really won't help, and no one online can offer anything other than a guess.

You need a doctor, and one that will get to the bottom of this.

Why haven't you seen a doctor?
