When to test

Jodie • IVF warrior - Expecting our rainbow April ‘23🌈🌈🌈

I’ve finally bought my ovulation sticks and I’m ready to get serious with ttc I’m on day 5 of my cycle and still spotting a little bit, how soon after your AF ends do I start testing or can I test whilst ending my period? I have roughly 29 day cycles so average ovulation day would be roughly day 14 for me
