Hi Marie, and welcome.
It often does take a while for a person newly gluten-free to start feeling better. Some other people notice a difference almost immediately, but this seems less common than taking a while.
If you are eating GF and still feeling intestinal distress it may be that other things in your diet besides gluten are not doing well right now for you. I suggest you try to avoid dairy products for a day or two, many people who go gluten free develop a subsequent lactose intolerance problem - often this is only temporary. If after a day or two you do feel better consider going dairy free for at least a month or two.
To get your gut under control you might want to steer toward foods known as less often involved in allergies. Rice is well tolerated for most people. I tell people that rice is my friend, and it is, a bowl of plain white rice
Celiac disease is not an allergy in the usual sense, since it involves damage done to the gut by the body reacting unwisely to a perceived threat (the protein fragments in gluten), but people with celiac disease sometimes have ordinary food allergies too.
Many people note they are feeling better in just a few weeks, some take 2 months, and a few struggle even on a gf diet.
I'm getting by OK on a diet that is vegan as well as gluten free. The two restrictions do provide some challenges, especially when traveling, but at home a high percentage of my meals are made from scratch. This ends up meaning they are just the way I want them in terms of seasoning and ingredients. I've become a better cook since my diagnosis because I use basic ingredients more often, and this helps the finished product be better.
Please keep us posted, and ask any other questions you may have.
