In UK should I be entitled to help?

I have 2 children youngest being 8 i'v been trying for a 3rd child for 3 years Iv had 2 losses in this time I have been telling doctors for years there's something wrong kept getting fobbed off I went to fertility clinic they said same nothing wrong with you keep trying and when I had my losses I noticed progesterone dropped in my bloods I asked for progerstone to help wich they reufed. So I goes for a laporoscopy 2 weeks ago found out I actually have endometriosis. I went back to the doctors who actually said her self she sorry on behalf of all the doctors i'v seen this shouldn't of happened and we probably could of prevented your loss if we would have listened 💔anyway they also tell me as I have 2 children I'm not entitled to any help trying to conceive is this correct? I know I wouldn't be entitled to <a href="https://glowing.com/glow-fertility-program">ivf</a> as you have to have no children but I thought seen as your suffering a disease they may help in other ways like medication cycle ?
