I'm pregnant should i be worried i was bleeding for two days and some pink skin flesh looking thing came out of me two times?

That is potentially a serious problem that should be looked into immediately. You should contact your primary care physician or gynecologist immediately. If you don't already have an established relationship with a physician you should go to the closest emergency room.

What you described is consistent with a miscarriage and you should see a doctor. Wish you good health!
