please calm my nerves!

i’m always super anxious for my period bc of pregnancy scares. it’s not supposed t come for 3 days according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and 5 days according to Clue. My boyfriend always uses a condom and has pulled out every time except for one. i’m not PMSing yet and my boobs hurt really bad when I am. can you still get pregnant if the condom doesn’t break? should i be worried? we have sex an average of 2-3 times a week. please help me!
