Pink spotting ad light cramping after sex!

Shelley • Married, expecting baby #6! We are already mom and dad to girls that are 21, 13, & 11. Our boys are 19, 7, & baby #6! 💙
I am 4-8 weeks prego, yes a wide span....Me and dh had normal sex (no ruff stuff) and went to sleep. I woke up a few hours later to pee and when I wiped I saw very light pink and peach on the toilet paper. I have never had this before as we were having sex every other day when I was pregnant with my now 6yo son. I am at the doc/ er and worried! Have any of you ladies experienced this??? I normally don't have any spotting or bleeding the entire pregnancy! Thanx ???
