Pink Spotting after sex?

Last night, I had sex and I went to the bathroom after and noticed some light pink spotting. It wasn’t discharge. Went to bathroom again like 20 mins later and it was gone and nothing today. So my question is, could this mean early stages of pregnancy? Has anyone had this happen. I’ve been having some other symptoms too. I always got really bad headaches with my other two and I have been dealing with bad ones this week. I’ll probably just go take a test but I wanted to know if anyone has experienced this before.

Thanks!
