Why should I do? Ovulation seems everywhere

I have a 3 yr old and I had a miscarriage in March and period came back April and I don’t remember the day. But in May it came on Mother’s Day and I thought I knew when I ovulated but obviously I was way off because it came like 4 days early in June it came June 7th. That’s my first time, I think lol, having a 27 day cycle. Before my miscarriage I was a 29-30 day. I’m not sure when I’m going to ovulate this month but my boyfriend and I have had sex every day this month including when I was on period, don’t judge me I was horny, and he has came in me every single time. But does that mean I’m on a 27 day cycle now?
