Last night I went to knotts scary farm. Total of 6 hours walking . No rides but walked a lot . Went thru mazes and everything and was fine just really tired. I did notice some lower back pain towards the end which always happenes when i walk alot (since i fell hard BEFORE i got pregnant; messed up my back)... When I got home I noticed some pink on my undies, so I wiped and it was light pink discharge . I haven't cramped or anything. I've yet to make an appointment still searching for a dr since mine relocated. Should I be worried. ?
