3rd transfer failed

My beta is tomorrow but I no it's a lose at this point, I'm probably gonna have to do a ERA & I'm terrified, I watched some YouTube videos etc..and it's gonna cost 1200, they say it hurts alot & idk if I can do it, when I had my HGS done it was very painful, the worst cramping after even Tylenol didn't help much. Is doing the era even Worth it????
