Locked out of iphone 7

I have locked myself out of phone . Passcode is incorrect after serveral attempts still not working. I tried to save some items in icloud when I was able to and when it let me still use thumb print. I tried to download photos onto laptop and wouldn't let me by pass the passcode , etc.

I really would luv to save my pics if possible some how . If I reset phone I have been told that I will lose everything.

In saying this I have an apple watch connected to it and can do messages etc.
