Anything for joint pain?

I’ve suffered with really bad pain in my knees, thanks to genetics 🙃 for awhile now. I usually take Glucosamine Sulfate for it from Vitamin World & it works great & helps a lot but when I asked my doctor at my 1st appointment he said not to take it anymore since I’m pregnant & that with pregnancy my joints will be better. I work 4 10 hour shifts a week & 2 hours into my shift everytime my knees start hurting extremely bad 😭 I don’t want to use acetaminophen my whole pregnancy. Any advice on what I could do?? Literally suffering. My doctor had no ideas 🤦🏻‍♀️
