I Haven't Had It In 4 Months

   Go to a gynecologist to calm down. If you don't have such early sexual contacts, don't worry! Delaying the cycle is not only due to pregnancy, but may also be due to some kind of stress, worries. Personally, when I was your age, I did not have a cycle for 5-6 months at first, until my body returned to normal.

   4 months is a lot to go to the doctor

   It is completely normal! But it may not come to you if you have lost weight or are under stress.

   When I was your age, it happened that I didn't menstruate for 6 months. I was overweight. I followed a special diet and soon my cycle came, it normally lasted a long time, almost 2 weeks. I went to a gynecologist, I have no problems. It's perfectly normal. Hormones are rampant in you. However, for your reassurance, get a referral from your personal gynecologist. In the worst case, it may be a cyst that is removed surgically, but it is a routine operation, don't worry! :)

   Yes, the first year your cycle may be a bit irregular, but 4 months is a long time, so go to the doctor. I don't want to scare you, but you may have cystic ovaries and have cysts for your cycle to stop. Some 1/3 of women have it, including me. It's not scary, but it's unpleasant. For this go to the doctor and you will know.
