Photos in my iPhone disappeared

Hello! I have a subscription for iCloud 200gb and this month i paid for it too late (in 5-7 days after exact paying date). All the photos in icloud were deleted from my phone so i still do not have anything in my gallery but i checked my icloud account in browser on the computer and all of my photos are there! I do not know how to return them into phone gallery so could you please help me with that problem?
