I can’t be a teen mom

Hey guys so my period is now 9 days late, I’m on the pill. I take Loloestrin. Usually, my period has been in the middle of the pack (not placebo) This is my third month of loloE. My doctor says it’s normal to miss a period but I’ve woken up a couple times this week nauseous and my boobs have been really tender and I’m freaking out that I’m pregnant. I’ve taken the pill within a 1H time window every single day. I only had sex once this cycle and we used a condom and pulled out. Please help me I’m sososos worried!
