How early can you test?

An

Hey mamas! I am currently trying for my first baby and this month is our first month ever trying 🤞🏼 my ovulation day on glow says tomorrow.. my cm is lining up with that but we’ve had sex every day up to this! When can I test? I know it’s good to wait but how early can I ??? What’s the earliest y’all have tested? 🙌🏼
