Bloody show?

Hi mamas, I’m a FTM and had a cervical check today. I’m currently 38+6 days. I’ve never bled after a check. About an hour or so afterwards I noticed some cramping, I went to the bathroom, wiped and noticed a little blood. It’s been just spotting since earlier today around 11. I am cramping like period like cramps and some dull back aches. The blood doesn’t have any mucus, and is brown. Thank you!
