When should I test?!?!

My husband and I TTC on the 2nd which was the day before my ovulation window opened. We tried again on the 7th; day before ovulation peak. I was supposed to start my period on the 22nd. So I’m officially 3 days late. Also I have fiber cysts on my breasts so they’re always sore/tender one and a half weeks before I start my period and I still haven’t experienced the soreness which has happened every month for the past 4 years.. should I wait until the end of the month before I test or could a home pregnancy test be accurate now? Please help! Lol
