Question for postpartum moms

Postpartum mom’s when did your period start to be regular again? I normally had a 28 day cycle. I had my son in February of 2022 and I got my first period April 25th to may 7th and then another period may 15th to may 21st and then another one may 31st. I don’t know when I should start again! I’m not sure when or if I’m even ovulating. P tracker said I ovulated on the 14th hubby and I had sex on the 11th and the 13th. So when should I take a test if I don’t know when I should start my period? I am not breastfeeding
