please respond :/

how effective is the pull out method with a condom on? I got off the shot about 2 months ago and still don’t have a period but I heard if you’re ovulating before your period you can still get pregnant. Only symptom I’m having pregnancy wise is peeing very frequently but that could be from a number of things. I’m only 18 so sorry if this is a dumb or a very obvious question. Just want to make sure I’m not being paranoid for no reason. I’m unsure if I’m ovulating but I think from my discharge I might be. Thank you to anyone who can give me an answer.
