Note that there is a difference between a wallet and an address. Namely, a wallet may control the keys for many addresses.
Checking the address you posted, it clearly has no bitcoins in it, as they have been transferred out to two different addresses:
If your wallet controls these addresses then you have nothing to worry about.
If not, then I’m sorry to say it appears your BTC was stolen. You’ll want to never use that wallet again, and it may be with spending some time trying to uncover how your wallet was hacked. Did you share login or wallet backup/seed info with anyone? Did you back it up to a potentially compromised email or Dropbox account? Etc
Your chance of recovering those coins is likely very slim, so at least you can try to learn from a past mistake.
