I can't believe I'm saying this - but I can offer some hope ☺️
My GP referred me for fertility investigations after a while of nothing and during this process I had a laparoscopy as they suspected fluid in a tube (there wasn't) but it did find endometriosis, and removed fibroids, adhesions and a large cyst from my left ovary.
The NHS route was slow, was an emotional and physical rollercoaster over a 4 year period. It's one of the hardest things I've ever been through, finding support will help you so much, whether it's professional, on support forums or friends that understand (sometimes hard to find).
However, last year we saw an acupuncture fertility specialist who asked more questions and got to to know me and my husband more than anyone else had before. She referred my husband for DNA fragmentation tests and a urologist (as after prolonged infertility it's rarely just because of one side) and found me an excellent endometriosis surgeon who did a detailed MRI and booked me in for a 2nd laparoscopy for excision surgery. Also basic lifestyle improvements, and targeted supplements based on a vaginal microbiome test we're all implemented.
Long story short, the surgery is cancelled as I got pregnant naturally after 5 years trying.
My advice is.... Try not to put your life on hold. This is something that some people just cannot time, and sometimes it takes a lot longer than we wanted it to! Try to do more of whatever makes you happy. That's my biggest advice. With the NHS appointments - you need to advocate for yourself, research online / speak to friends. The more knowledge you have the more it will help as they do get it wrong sometimes.
The past year I put a lot of effort into trying to make some kind of piece with a life without children, find the positives and I think that helped take the pressure off, and made it one hell of a shock now I'm having to forget all those reasons! This is something that you only start to do after years though - you're still very early days and there's so much hope! Look up the stats of how long it takes people to conceive, it's roughly something like 90% of people conceive within 2 years, it's good stats!
What helped most was our acupuncturist that had specialist training and referred us to people that were great at their job.
I wish you all the best - if there's anything I can do to help please ask away. Sending hugs - I understand how horrendous a thing it is to go through, I hope you find some support to help you through it x
