A lil worried

Im 10 weeks and on Saturday night i had intercourse and bled some after wiping. The next morning there was light pink after wiping again and a bit of cramping. But the rest of the day was fine and been okay since then. Today i wiped and was a tiny bit pink again. I called my Dr and they said it was completely normal after sex. But if i was concerned then head to the ER. Im praying everything is okay. This is my 4th baby and never had this happen before after having sex. Anyone else experience this?
