Hi. I am 17 years old. The last time I had a normal period was around January 14, 2011. I had sex on January 21, 2011. Ever since I have skipped February and March. I asked my ex boyfriend if he had ejaculated but he said no and I asked him if he had pre-*** and he said that for some reason that does not happen to him.
I took 3 pregnancy test about 2 weeks ago bought from the dollar store and all three were negative. However I keep getting the pain like if I was on my period but no actual bleeding. The pain comes and goes but usually it is in the morning.
The last 2 months I have also felt extra tired and keep falling asleep. I take 6 AP classes and 3 college classes so I am guessing it is the caused of school stress.
I am very scared and do not know what to think anymore. Please help me.
