I found that very helpful - thanks ! (I'm not the OP).
@atgnat I have worried about all these things too. And I did feel worse on the wrong dose of HRT because I was, as you say, essentially adding fuel to the fire with greater fluctuations because it wasn't enough to stabalise anything.
I know you always hear all these women who say they started HRT and felt fabulous 3 days later, but many many people have to keep trying different things until they find what works. Most people don't feel great immediately, many people feel worse initially.
It is a really hard thing to do because 1) you are initially stirring things up by adding more hormones in, and your body and brain have to adjust to that each time and; 2) you have to wait such a long bloody time for it to settle down before you can conclude it's not worked and you need to try something else.
For me, stability looked like 100mg patch (max dose) and 200mg utrogestan continuously (double the normal daily cont dose). I had to work that out very slowly and incrementally. You figure it out yourself along the way, if you're not already doing it I'd really recommend a diary.
I had HRT prescribed initially by a private meno specialist, I was so uncomfortable about it being private I booked an appointment with my GP practice specialist and asked her to tell me the stats about risk and talk it all through with me. I'm very lucky, she's very current with her knowledge. It was my GP who suggested continuous utrogestan is better for women with menstral migraine, and she was right. (You can use it continuously by the way, the risks increase slightly if you're on it for more than 5 years, the main reason they don't give it to pre-menopausal women is because you're likely to get breakthrough bleeding which needs to be investigated).
I think it is really common to feel like you do when you start getting menopause symptoms at a young age, even if you also know that you have a strong family history of early menopause. In my family, there is also a strong history of osteoporosis- it never occurred to be before I spoke to my GP that these were correlated, but she was completely sure HRT was the right thing for me and explained it really well. Logically I know that is a completely sensible way to think, but for some reason I still have a wobble over it - I think that is part of peri, you feel more worried and unsure, particularly about your own health. I completely understand your desire for some concrete way of knowing you are doing the right thing.
My issue is not low overall levels I don't think (although they do get low, as shown by one pre-hrt fsh/lh test). It is massive fluctuations. I needed a high dose of hormones to bring the baseline level up high enough that when they dropped, the drop wasn't so great. As my own hormones are declining, which they definitely are, that stability I get from the patch is increasingly beneficial. I did feel worse for a long time before it got better, but I knew I felt so terrible off HRT that wasn't an option. There was a bit of blind faith involved.
If you've ruled out other possible causes - iron, b12, thyroid, then given your family history, age and symptoms - there's no reason to think it is not perimenopause. It is the most likely explanation.
You don't have to use HRT if you're not comfortable with it, but we will all go through menopause at some point, it's a process and a transition and at no point before your periods stop will there be any certainty to it. Both my Mum and her mum had completely regular periods until one day they just stopped. Both of them had osteoporosis- you can't avoid risk by not doing anything.
It is very unpleasant to wake up several times a night, have violent mood swings, brain fog and the feeling you don't recognise or trust yourself anymore. We hear a lot about hot flushes and delayed periods - but this might not ever happen. It doesn't mean the symptoms you've been having aren't very valid and real signs of perimenopause, they're often the thing people find harder than a hot flush, or 10. I know I do.
Ultimately it is up to you whether you continue to pursue trying to find a solution, or decide to just live with the symptoms until you feel more sure, or they get so bad you can't cope with them anymore.
I think you might really benefit from a discussion with a private specialist - worrying your GP might take your HRT away from you if you're honest isn't going to help you feel reassured, and feeling confident in your plan is important. Find someone with some decent medical knowledge and lay all your worries out in front of them. Trusting someone to use medical judgement is the most certainty you are able to get I think.
I do really understand where you're coming from. My experience has been very similar to yours.
