Help! Can someone explain? I’m 15

This month my birth control came in 4 days late this month. The pharmacist said to just start from the day I got it (Thursday.) I ended up taking two pills everyday until I was caught up. I had sex twice this month. Once without a condom (still pulled out though) and once with a condom. Tonight my discharge was stretchy and maybe clear? I’m not quite sure what’s clear or not. I’ve been taking birth control regularly since September. Should I be worried about possibly being pregnant?
