Pregnant and spotting during sex

I have contacted my doctor about bleeding before.

He told me it is normal as long as there's no red blood, enough to fill a pad.

He did not suggest not having sex but did mention not using a tampon. He also said to keep it easy.

We decided to avoid sex anyways, and chose not to have sex until about a week after the pink was completely gone. It only lasted about 2 days.

This week we have had sex about 3 times.

Today we noticed about 4 drops of red blood on our bed.

When I wiped in the bathroom it was pink.

I tried calling the doctors, but then realized it was Sunday. I was thinking to go to Urgent Care but they told me only to go if there's a decent amount or cramping with it when I called last time.

Has anyone also had anything like this?

Would anyone suggest going to urgent care even if it doesn't get worse just incase?

I plan to avoid having sex and calling my doctor tomorrow to ask about it.
