3 months without a period


Im 16 years old and started my first period in February this year.

I havent had my period since july. In mid august i had unprotected sex for 3 mins.

Now i havent gotten my period at all. Ive taken 3 pregnancy tests and they have all been negative. I have no symptoms, i havent gained any weight, and I dont feel pregnant.

If i was pregnant i would be at 14 weeks. I had a blood test done 2 weeks ago but i still havent gotten the results.

Ive been scared shitless about this since august.
