bloody show

Brittani • 29.. Married 2012.. Boy mama💙 and another 👶🏼 on the way!
39 weeks and 2 days and just woke up to pee and had a good amount of blood. My husband and I did have sex about 7 hours ago before dinner. Is this from sex (which has never happened before) or is this my bloody show? I have been cramping ever since the sex. Thanks!
