TTC with irregular cycles

So today is CD 37 for me... according to this app & AF is due tomorrow (or 10/24 on Ovia) - I backtracked to see how my previous cycles have been & realized I'm super irregular, I've been TTC for about 6 months but I have gotten a lot more "passionate"😜 about it this month... my last 6 cycles have been 25days then 22,28,30 last cycle was 38 days & today is CD 37!!! Just curious how many others are irregular... does this effect our chances of conceiving or no if we know when we're ovulating? I did OPKs this cycle which make me 14DPO today, I have taken 3 BFNs earlier last week & I feel as if AF will be a no show!! This will be my 3rd child & I just "feel pregnant" 🙄🙃😌 going to wait until after the 25th to test... hoping the other tests were just too early🤞🏽🤞🏽🤞🏽
