Need help. Confused!

Nikki
So I had what I thought was my period a couple of weeks ago n only lasted 3 days. This time it's different than any other periods I've had. I was actually able to use panty liners instead of tampons n pads. Also I didn't bleed like normal it's more like blood clots, only when I go to use the restroom though. Now I feel like I've either got something growing inside or something is, wtobg. Stomach is tender to touch n hurts when I put pressure on it. Breasts don't really hurt (yet) but nipple feels a Lil sore. I have cravings but can't really eat. Used to love Asian food but now American foods siu b d's n taste better. .what could it be. ..
