PIP Review submitted end of May 26, no news yet, could I use the Gov1 site?

Hello, I am a bit anxious about my PIP review as it will be 4 months since it was sent in, at the end of this month. I heard people talking about the Gov1 site for extensions of PIP awaiting review and wondered if the site also gave results for those who have submitted reviews already??
I know I could just create an account and look, but I am scared to "put my head above the parapet" in case it is the wrong thing to do...may sound paranoid but the DWP can be difficult...

I am also worried about a planned family holiday to Europe over a week or so at the end of October as of course I have to notify the DWP. I am concerned that they may contact me for an interview or phonecall in that period when I am away without my file of papers, and I am thinking of not going. But I would prefer to find out if there has been a decision as some people have said they found a decision online somewhere and they hadn't been informed by letter yet...
Could anyone advise please? Thanks
