Hi I'm 17 yes old and a girl. I have intercourse regularly and about 2 months ago I had a period. But not since only a little spotting about a month ago and it was brown. Why does my stomach hurt all the time and especially when I put pressure on it. This is like the 3rd week I've had frequent urination and I get so naseous but don't get sick. I get so dizzy and light headed when I stand up even after I eat. I get really hot all the time and my hands get sweaty. I can't stand the smell of certain foods all the time. There's even starting to show for a week now blue veins around my nipples and up my boobs and they get so sore and tingly alot. Could I be pregnant?
