Recently deleted photos

Hello, please help me solve my problem. I bought an iPad and installed my icloud on it, all the photos from the phone started uploading there automatically. In fact I didn't want them there and I removed them (but I checked before if they were deleted from the phone) Recently I went into my gallery on my phone and out of all my 2000 photos there were 100. Is there any way to get them all back? There are a lot of valuable photos here for me, I am really asking you!
