Cycle

So I’ve been taking this Conception stuff for fertility and ovulation. Since I’ve been taking it my period have become more regular when I count the day from my last period to my next it’s about 28/29days. But in the app calendar it’s saying this month I won’t start for 3 more days which is 32day cycle. Im just confused on if I think im pregnant should I wait until the end of the month to see if I do start my period like the app says or since im CD30…would it be safe to take a test? Im super impatient….but then I don’t want to be disappointed or have a false negative if it’s too early.
