First month TTC

Mrs. P
Ok, I need everythin, I been on this app for a lil min n my bf wants to try for a baby. I see dpo, cm, etc. I kno days past ovulation and cervical mucus but give me the skinny on it. I dont think I have an idea of when I ovulate. Wat all should I kno to have a successful or at least a good try at it?
