Spotting after BD

ET ☝️💫 • Boy mom trying for #2 🤞

Last night DH and I BD. I’m 11 or 12 dpo. AF should be here on the 17th. It wasn’t rough or anything I didn’t experience any pain. Afterward though I experienced some light pink spotting which stopped during the night and hasn’t returned. I’ve never experienced this and I was wondering if it could be a sign of early pregnancy?
