Hi everyone!

I’m going to try and not waffle on too much lol!
I’m a 33 year old woman and since September last year I have had high FSH levels and up and down LH & oestrogen levels but have had a previous episode in 2018 of high FSH levels with completely absent menstrual periods which sorted itself back out after 4-5 months and everything went back to normal, normal periods and all! I also have a slightly underactive thyroid that’s been managed by medication for the last 1.5 years.
This time it hasn’t gone back to ‘normal’. Last July my periods suddenly became too frequent - every 1.5-2 weeks and my pms got very severe along with heavier discharge. At first I had vaginal swabs and an ultrasound scan which all came back clear. Inbetween 2018 and now I’ve had very similar symptoms with my periods just suddenly coming way too regular but only last a few months at a time but my hormones were never checked and my GP put it down to my thyroid which was being observed and not treated at this point as my levels keep dropping then going back to normal. The endocrinologist said eventually that my thyroid wasn’t under-active enough to cause such period issues.
Then in September last year the GP decided to check my hormone levels and realised my FSH levels were very high (I believe in the 50’s) and my LH levels were slightly higher. So I was referred back to the Endocrinologist.
Fast forward to now! Still exact same symptoms (too frequent heavy periods) and very occasional hot flushes and bad pms (and heavy discharge). I’ve had a few frustrating phone calls only with the consultant since last year and countless blood tests. The consultant just kept telling me to monitor my symptoms as they weren’t sure if I was going into early menopause / perimenopause but I finally saw someone in person yesterday who was very perplexed as normally if I was in perimenopause my estrogen levels would be lower when in fact they’re a little high this time. My FSH levels were also at 39 and my LH levels around 21 when I had my blood test a few weeks ago.
I’ve now got to have a MRI brain scan to check my pituitary gland and some more thorough blood work done. Which my anxiety is freaking out about!
I’m still no way in finding out what’s going on but I am wondering if it is pituitary related or just that my hormones are a bit all over the place as I am actually in/going into perimenopause.
Not sure if anyone can relate whatsoever? I’m just so fed up now!
Sorry for the amount I wrote! I did try to keep it short-ish
