Confused about my random cycle

anon • 🤫
I don't ovulate until at least day 16 of my cycle (this month it was day 18) and i don't know if this is ok or not? I seem to have 28-30 day cycles that are regular but ovulate so late that my DPO are so short?! 
Pregnancy tests advise to take ths test at least 15DPO but i dont get that far?! I am 9DPO and AF is due in 2/3 days.... What the hell?? Is this normal? I don't think i'd ever be able to take a test before i miss AF as it would always show a false negative?? So confused!! Any advice greatly appreciated!
