I think I know which forum you mean, it recently died and doesn't exist anymore.
Some of the posters were madder than a box of frogs and were rabid with weird conspiracies, like Kate used surrogates for all 3, Carole bore George as well as Ben Foggle's wife and his sister, the Middletons blackmailed Will into marriage with Kate, Kate only gets fake jewels to wear from Liz and other batshit crazy stuff, most (all really) which didn't add up and was conjured out of thin air because separate occasions fit together to be spun into a new tinfoil-hat story. Because if two friends end up at the same hospital, one of them must be a surrogate. Makes sense.

Then they had "proof", which I bet was some of their own accounts, sounded just like them. One commenter would often post dm comments as proof how the theories and "truth" exist beyond their crazy rocker, but the wording etc was exactly the same as theirs....
The same is happening around Meghan, claims of surrogacy and that she blackmailed Harry into marriage and got fake jewels to wear...

There are claims of Kate at a fertility clinic in LA in 2011 but I never saw pics or anything else, beyond the crazies claiming this.
London has top rate fertility specialists and it doesn't make sense to visit a fertility clinic a continent away and then never go back.
Kate was pictured arriving/leaving at her own gynaecologist's office when she was pregnant, which I deem as normal as can be.
