24 weeks light pink spotting

Jaimie

FTM. It is 4a.m on a Sunday here. I just got up to pee and when I wiped there was a small amount of light pink spotting. I wiped again and there was no more. My husband and I did have sex yesterday. Tried once and it was painful. Tried again later and it worked out good. Could that be why? Even hours afterwards? My doc is closed on Sunday. Should I call someone else or go in?
