The only reason progesterone is typically prescribed cyclically in perimenopause is in an attempt to create a regular bleeding pattern.
It achieves this only a minority of the time anyway in my experience.
If you don't mind the possibility of a less regular bleed pattern, there is no medical reason why you can't take the progesterone continuously.
This is usually recommended from the start for those with cyclical symptoms such as migraine or endometriosis etc.
However practitioners who lack knowledge and confidence will often stick rigidly to the flow chart which signposts cyclical for peri, continuous for post.
The dose for continuous is half the dose for cyclical eg 100mg nightly vs 200mg nightly.
This means taking the same number of capsules over a 4 week period regardless, so with your existing prescription it will already be in your gift to take it continuously if you prefer.
