I am 19 years old.I started my period when I was in 6th grade. My periods have been normal (for me) and regular lasting about 7-8 days. But about 2 months ago my period started lasting 11-12 days. And it wasn't as heavy as normal. My period after that lasted 12 days as well. A little more heavy but not much. Then my last period I just had lasted 19 days. It was a nomal period for me at first. After the 10th day I started spotting. When I would use the restroom sometimes there would be just a little blood. Sometimes nothing at all, sometimes a bright red but just a little, then other times it was a thick brown/black color. I have been a lot more tired latley, hungry, moody, emoational, bloated, sore nipples, feel like throwing up but never do. People tell me I'm pregnant but every test I take is negative. What do you think?

Probably a stupid question but you wouldn't believe what's asked - have you had sex, protected, unprotected?

Well, then, of course you could be pregnant. Get tested. No one here can test you.

Since every test you take (and I assume you're taking home pregnancy tests) is negative, may I suggest going to the doctor and having a blood test performed. Even if you aren't pregnant, the whacked out periods may be a cause for concern and should be mentioned to a professional just to be safe.
