Did anyone’s cycle length change after their miscarriage?

I’ve always been a regular 30 day cycle. I miscarried at the beginning of March. I ovulated April 3rd. Got my period April 15th. Predicted ovulation day would be May 1st based on my normal cycle. I took a opk on the 27th. Light second line. 28th darker second line but still negative. Normally it continues to get darker until positive. 29th the line was a lot lighter than the day before. I use tests at 2pm. On the 28th I had EWCM but only for the one day and it stopped. So I’m confused on what’s going on. If I missed ovulation this month 🤷🏻‍♀️ if I had a normal 28 cycle then ovulation would point to the 28th. We did the deed last night (29th). Am I out this month? 😫 I’m going to continue with the opk still. I’m just confused.
