the company says if i have regular period i should test on day 19,20, or 21 of my cycle and if i have irregular i should test five days before my next period. My periods are somewhat regular like I know which week I will get them but not to the exact day so I am unsure which day I should test on? Any thoughts? I want to make sure to do this right since I am spending so much money.
