Has anyone experienced late periods whilst being on Mounjaro or after they came off it? If so how late?

Mine was the other way round. Had been on the Depo for about 10 years no periods then randomly got one when I was on MJ last year!

Periods can be affected by quite a few things when you’re losing weight or your routine is changing, so I wouldn’t automatically assume it’s the MJ itself. If there’s any chance of pregnancy, I’d do a test just to rule that out, and if your cycle stays unusual or you’re worried, it’s worth checking with your GP. I’ve found that keeping track of dates alongside weight and other changes can make it easier to spot a pattern

There seem to be quite a few things that can affect your cycle, so I wouldn’t automatically assume a late period is caused by MJ. If the change is unusual for you or keeps happening, it’s probably worth mentioning it to your GP or prescriber
