Feel like I am going mad

Hi, my story is a bit long winded so I will try to keep it short. I'm 44 and since I was 36 I have had so many gyne problems like periods every 2 wks,painful sex, bloating that lasts longer than 3 wks and pelvic pain at this point I can honestly say I have more photos of my insides than I have of my face haha but other than a chocolate cyst 8 yrs ago nothing is ever found.

I had a scan colposcopy and exploratory exam under GA in February last year and mirena coil fitted then 2 wks later put on hrt, which was amazing for 3 months but due to shortage they have had to change brand and dose every 3 months since a yr later and I'm on 100 mg evorel but gone bk to bleeding every 2 weeks headache and a weird flutter feeling in tummy that makes me feel sick (only way I can describe it is like when you get bad news and tummy goes funny) so now gp sending me for a scan again on 20th July and even though I know it will be clear again I am scared has anyone had similar symptoms/problems as my Male designated doctor is prone to making me feel like a fraudster (lady dr is fab but very hard to get appointment with) no dr has ever said anything that explains the symptoms and I am struggling with it all every scan is fast tracked so the worry is driving me mad ..thank you for reading
