Beardie getting Darker. Help!!!

Yesterday my beardie started getting blacker Than normal around the night, I took this as nothing that important and took her out until she got lighter again ( though she was just stressed that I didn't took her out much that day ) At night I went to her to see what was doing and she was scratching the glass but when I turned off the red light for 2 mins she went to sleep. Today in the morning I woke up to find her on her basking spot ( Which is unusual as Im getting her adapted to a new rock for when I move her from a 20 gallon to a 40 gallon tank and she doesn't bask a lot as is too close to the roof of the tank and got her another basking spot though that night I accidentally put the basking light on the rock. When I came back in the afternoon she was still on the rock ( which I though was a little too hot for her ) She was also blacker than normal. I took her out and gave her a bath and she regained her normal colors. She pooped today and though I didn't see it my mom says it was of the normal huge size they normally do . She hasn't shedded since 4 months ago I think when she stopped having her "Baby sheds" when she shedded every 3 weeks. Thats the only thing I think she might have. She hasn't moved a lot today though when I take her out of the cage she doesn't have problems moving. I changed her diet last week to instead of giving her around 4 crickets per day I give her 10 every other day so I don't know if the change of diet might be a problem. I should add she was normal until yesterday night
This photo is her when she stoped basking for a moment today in the morning.
Can somebody tell me if she may have something ?

Update: She doesn't wants to eat crickets. I don't know what to do to make her feel better if she feels bad.
