Protected sex, Late period??

Emily

Hi, I'm so scared. I'm on birth control, he wears a condom and pulls out. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says my period is late by a day but on my pill pack, my inactives were last week. I'm so scared as I'm 18 and leaving for college in a few days. I've had cramps and other PMS symptoms but nothing. A few days ago I had a little blood when I wiped in the morning and then nothing. Please help 😭
