Hemorrhoids!!

I'm fed up with being in absolute agony with my hemorrhoids day in day out. I've suffered with them for 6 years now and since being pregnant they've just got a lot worse. I'm in tears most days because of the pain. I've been to the doctors so many times and they just say the same things. I don't know what else I can do. I've used Anusol, Anusol with steroids in, preparation h, suppositories, fibre gel, laxido etc. Nothing helps!! Please can someone give me some ideas on what else I can try? I'm 24 weeks pregnant and dreading giving birth because of them😔
