Question about cycle

So ladies ! I went off BC last July . Got pregnant late October , miscarried December 9th, I had 28 days cycles ... since my MC my cycles have been 24 to the day (I’ve been starting 4 days early ) so I went and changed my cycle in glow to 24... has this happened to anyone ? Also, I realized if I conceive this next cycle I would have a late November baby ! Prayers that happens .
