TMI. Oops on day 21 of my cycle

On day 21 of my cycle. Had sex for a few minutes without a condom then he put the condom on when he was about to finish 7 days ago.. and had only protected sex since then and now I'm getting bright pink spotting. Hoping it's an early AF but I never spot pink! We are totally fine if I'm prego but we were hoping to get prego on our cruise in June lol.
