When to test with irregular cycles

Iv never been late always 100% on time unless iv been pregnant well until i had my last Bub I stopped breastfeeding May 2018 and got my first period June 2018 since then my cycle is irregular (there was 45 days between June and July and then everything after)

45 June to July

36

32

35

32

33

So anyways the past 2 months iv noticed a few hours of cramping and just assumed ovulation (we were not ttc)

As of 2 days ago we have started trying for Bub 3 and today I started getting the cramps so I decided to get a ovulation test and it’s positive (test is darker then control) and since entering it into glow it’s changed my expected ovulation from 22nd to 26th and expected period from 5th feb to 9th

If it hasn’t come by 9th Should I test or should I wait? What day would you test?

Please don’t think I’m stupid like I said before iv never been late and never been irregular so I don’t want to waste money on tests if I’m just testing to early anyways

Thank you in advance
