spotting after sex?

Mina • taurus moon&sun - scorpio rising bby 🇹🇭

so i’m on birth control (the implant/nexplanon), and i had sex yesterday without a condom. everything was going fine, no pain or anything

however i woke up today to go do a number one and when i wiped i have a neutral pink spotting coming out. i’ve also been struggling to wee too

should i be concerned?
