Am I pregnant ?

So on oct 24,2019. I had intercourse with my boyfriend. And we had a scare that one of them might have broke but they didn’t cause we checked but to make sure the next day I took take action (emergency contraceptive). I had a little side effects nothing special and then my period came early on nov 7 2019. I knew it was since I was cramping that morning. It basically came exactly 2 weeks after I took it. It was like regular but kinda light at first then got heavy, lasted for 4 days. But had brown discharge for 2 days after. It’s nov 25.2019 and lately I’ve been having stomach ache and hard cramps my period doesn’t come until 11 days . And I’m scared maybe I could be pregnant since my discharge is watery and white . Don’t understand. Maybe if I’m still having side effects or maybe ectopic pregnancy ? Help!!!! ASAP
