Is this normal? Pic attached

I’ve been having spotting on and off. I’m about 4-5 weeks. This last Saturday, my husband and I had sex and after I noticed actual blood, red but not heavy. It subsided. But today, I’m having on and off spotting. Again not heavy. Attaching a picture today of what it looks like. I do have an appointment with my doctor today so I plan to ask then too but I just want a peace of mind.
