Hey, im 16 and missed my period in august and September. I had unprotected sex on the 12th of august. Ive taken 2 pregnancy tests since then and they have both been negative. One was 2 weeks ago.

I have no pregnancy symptoms, if i was pregnant I would be at 9 weeks. Though all of September and the end of august I was overseas in japan and just got home yesterday

I also only started my period this year in February.

Someone please help!
