Okay so I'm 19 years old. I had my normal period on January 19 2015,I was supposed to have one in Feb it never showed up then the same thing in March.As of today March 27th I'm 39 days late on my period.I have had every pregnancy symptom ever it feels like:nausea,super fatigued,frequent urination,mood swings/super emotional,cramps,head aches all the time,I'm pretty over weight but my fiance says my stomach is harder than normal and it feels like I'm always really full from the inside,I eat all the time,some things make me nauseous,things I liked before. All this being said I have taken probably 10 pregnancy tests and they all say negative,but I'm late,have all kinds of symptoms,people keep telling me they think I'm pregnant or that I look pregnant,and I generally feel pregnant! Help someone tell me an experience like this or advice or something
