Thick uterine lining - terrified

[Overthinker13]

Hello,
Back in January, an ultrasound revealed a 12cm complex cyst on my left ovary. I had major abdominal surgery to remove it, along with the fallopian tune and ovary and then had the agonising wait to get back biopsy results. Thankfully they were clear and the cyst was benign.
Six months later I am still having pain in my abdomen particularly around the incision and was sent back for another ultrasound. They found a simple cyst measuring 4cm and said they would bring me back to see if it went on it’s own.
I went back for another ultrasound a couple of weeks ago and was delighted to hear it had burst and my body was getting rid of it.
I thought that was it but I got a call this week from the consultant who said that my uterine lining looks too think on the ultrasound and that I now need to have a hysteroscopy to check for polyps and possible biopsy.
I am so petrified of it being cancer. It feels as though I’ve been in limbo all year and I’m
Struggling to stay positive at the thought of any more biopsies.
I am 36 with a 3 year old. Has anyone had a similar experience with a thick endometrium? I have had irregular periods my whole life but dont bleed between them. The only spotting I ever have is very light occasionally in the two or so days before my period fully starts.
Sorry to unload like this, I’m just in a super bad place with all the worry.

Anyone?

No experience to offer I am afraid but virtual handhold until those who have arrive

Last summer I had uterine thickness of 18 cm in spite of bleeding continuously for 3 months. I had hormonal imbalance and estrogen way out of control so I was continuously building the lining and because the lining was too so was shedding it in light to heavy bleeding. My gynecologist prescribed me ovral , that cleared the thick lining but had flooding during period. Eventually had a hysteroscopy and everything was clear , no polyps either. Now have a mirena.
My estrogen dominance and hormonal imbalance was caused by a 6 cm ovarian cyst. It was removed at the same time as hysteroscopy. So my advice is don't worry too much , may be you have hormonal imbalance as well.

Thanks for your reply @Literallyfedup I had thought of estrogen dominance myself as for one I grew a 12cm cyst but also because I get a lot of cystic spots on my neck which i read can be from estrogen dominance. I'm pleased to hear the outcome of our investigations didn't uncover anything nasty and really appreciate the positive story.
