I am 19 years old and I have not had my period in three months. I have always been irregular but lately I've been having a lot of clear cervical mucous. I am not sexually active so I cannot be pregnant. Is there something wrong?

We really can't diagnose you online, it's simply not possible to do so.

There could be many reasons your period has stopped, it could be weight loss, weight gain, stress, illness, infection, and the list goes on and on.

If you're concerned, see a doctor.
