pink and brown

Rudie

i am 14 weeks pregnant and yesterday i went to the bathroom and tryed to have a bowel movement and nothing was coming so i wiped and i had brown discharge on my tp not much but still noticeable. i went to work and went to the bathroom later on in the day and i had a light pink discharge on my tp it was more then that morning and it only lasted a little bit then went back to the brown discharge this morning it doesn't come of on the tp but its still there and not much. i had a miscarriage a year ago and im freaking out but cant go see my doc till monday. is this normal or not
