Help could i be pregnant

Help! I just got my nexplanon implant removed the 29th of jan and i was told its very easy to get pregnant so i been using condoms(although I've never used condoms before so hopefully i used it correctly) until my period starts so i can take my birth control pills and a day before i was supposed to get my period i had light brown/light red discharge i thought my period was coming so i was happy but it hasn't came and im 2 days late and i know im probably overthinking it and i should wait but ive been having white discharge latley and more than i would think i normally would and i searched up those symptoms and those are usually early signs of pregnancy but im not sure because its similar to period symptoms , should i be worried or am i overthinking it?
