help! 😳

So... my boyfriend visited me (we are long distance) and obviously were having sex. I had just ended my period when we were having sex, and now my period is 10 days late. I have discharge and today I woke up spotting. My period is usually irregular but I'm so scarwd because I'm spotting! Any advice or has anyone been through this? I'm taking a pregnancy test tomorrow but for now I'm spazzing out.
