Not sure when to test

Hello Ladies,

My husband and I have been ttc since April. I was on the birth control pill for 8 years so once I stopped taking them my cycles were a little crazy. The first one was 36 days then 32 days then 32 days again and my last cycle was 46 days. My last period was 1st - 4th of July. Glow has me estimated to start my next period on August 5th but my other app has me estimated to start on July 29th. So When Should I test?

Thank you for any help
