My cycle has been wacky since having recurring miscarriages my last miscarriage was on December 31st and I received one period after which was on Jan 27th shown in the screenshot

if I put in the <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">due date calculator</a> for my last period it says due date November 5th

(for a 30 day cycle which is my normal cycle but haven’t had in a while )

but when I put it in for a 21 day cycle which I think I might’ve gave it says October 26th??

How long do you think my cycle is ?? I know it’s hard to tell off these but Ive has 3 miscarriages consecutively before now so I literally have no idea
