Pregnant?

Lexi

So about a week ago I had unprotected sex, and the day after I took the pill. But now I’m having a lot of pregnancy side effects, should I take a test or what should I do? My period tracker says I’m like 2 days away from getting it. But the last time I did get it it was late by like 12 days and only lasted for 4 days. I don’t know if that will happen this time or what. Please I need help!!
