Hi elsie001 and welcome to MM
I know various ladies have responded but I don't think any have actually answered your question.
You don't tell us much about yourself e.g. your age, why you need progesterone etc? Are you in early peri menopause? You are describing some typical early peri symptoms in regards to sleeping? I think it is unreasonable to expect to feel good all the time and all treatments will have some side effects or problems - it's usually a matter of finding a balance of more positives to negatives with HRT treatment. You don't mention whether you will be using some oestrogen alongside yet?
If you have been advised to have the Mirena due to heavy periods or erratic bleeding then this can be a good option. The advantage of the Mirena can be that, when and if you need some relief from menopausal flushes and night sweats, you only need to add some oestrogen in gel or patch form without using other progesterones - this can make life easier when trying to find the right amount of oestrogen you need. You also don't need to worry about contraceptive protection during the peri stage when there is still a chance you can get pregnant.
You are concerned that your period is due when the Mirena fitting is scheduled - clearly you are still getting regular periods? I would simply phone the clinic and find out whether they are happy to fit this while you have your period or reschedule this appointment. Alternatively you could probably be given some progesterone in pill form to delay your period - you could speak with your GP about this - probably with a phone appointment. You would only need to take these pills for a few days so I wouldn't worry about side effects at this stage.
Others have flagged up the the issue around progesterone intolerance but many women get on very well with the Mirena because less progesterone goes round the body systemically so get fewer side effects as a result. Some women are so progesterone sensitive no progesterones suits them and this can be a real problem.
Utrogestan has been mentioned and this is the most natural progesterone, however using this alone will not offer conceptive protection and is not always strong enough to control erratic and heavy bleeding. Utrogestan has a sedative effect which can be a problem for some women - so being natural doesn't mean it is better tolerated by all. I am 59 so Utrogestan pills alongside oestrogen in gel form has been advised for me (especially due to my age) but I am finding I get some breakthrough and erratic bleeding on this, so I am doubtful this will be appropriate for you at this stage.
I hope that helps DG x
