What is this?!

Stephanie

I'll be 6 weeks pregnant Friday. Saturday, yesterday and today I have thrown up these red things. It's usually about 5 or 6 of them. I have no idea what it is. I have NOT drank or eaten anything red or remotely close since Saturday morning and that was just a cup of strawberry pedialyte which I threw up. I know it's gross but I have to ask if anybody else has seen this??
