Period & Sex

Hello! So I wanted to just clarify some things, my husband & I got married on 2/23 and we had sex for the very first time on our honeymoon. My period wasn't supposed to start until 3/3 but it started on 2/25 and lasted until 3/10. My normal cycle is 27 days, periods are a week long. I've been spotting ever since I finished my period. Is that normal/expected? I assume this craziness is because of me having sex for the first time. Thanks for your clarification!
