One thing is certain in perimenopause, your periods will become erratic then eventually stop unless they are kept going artificially.
My periods spent a few years being irregular before stopping for that all important year. Now I only get periods with hrt, but they are still irregular, sometimes starting before the utrogestan has finished, this month my period was late, started five days after the utro stopped.
At first they had me on conti, but I bled every month on that too so they switched me to sequi, mostly because I don't want to take progesterone all the time.
If you don't bleed, I don't think it matters so long as you took the progesterone, it might mean your lining didn't build up enough to shed.
It could be raising your oestrogen levels without raising the progesterone as well caused the lining to stay put which isn't good, in that case you'd need more progesterone,
Or it could mean you need more oestrogen than you have now to build enough lining for a period.
The possibilities are endless enough that most of us rely on trial and error and just try to be tolerant of the doctors who think they understand it while all their predictions fail to come true in practice.
