Wondering what this could be

Katie

I’ve been having spotting on and off, nothing heavy. Mostly light brown and sometimes dark brown since I found out I was pregnant. I’m about 5 weeks. Saturday, I had sex with my husband and I started getting bleeding after that, it was red, and subsided about an hour-2 hours after. Yesterday and today, I’ve been having spotting again, pink, brown, and brown red. Attaching a picture as well. Is this normal? First pregnancy and I don’t know what’s ok and what isn’t
