so I'm 21 weeks and i have been cramping badly for 3 weeks now....period cramps times 1000....i also believe it was my mucus plug fell out 2 weeks ago. so I called the doctor and the doctor said the chances are it was just discharge because there's no blood and then the cramping there's probably Growing Pains. but now I want to go and take a shower and my underwear was wet and appear to be a reddish brown color. so instantly I thought was poop or something. I did not know so I smelt it. it smells like old period blood. but when I wiped there is nothing and I'm gone to the bathroom about twice and still nothing when I wipe. do you guys think I should be worried call the doctor again or just ignore? I could just be paranoid because I've had a miscarriage I've had a preemie who was almost a stillborn. and then im extremely high risk pregnancy....i can't go to labor and delivery till 26 weeks and my er sucks and it's the weekend.
