[My VA claim estimated completion date changed to 05/03/2019- 04/30/2019 Good sign or bad ?]

I called my local Veterams Affairs office and they told me that I'm waiting on my cover letter for my claim 05/06/2019 and to expect a decision letter this week. Since they are waiting for this "cover letter" my claim switches to pending for decision and new estimated date 05/24/2019 - 06/18/2019. I know my status will bounce around, this just let's me know my claim is moving.

It's now May 3 3019. Still pending for notification and past estimated completion date April 29th. If it were negative would o would have heard something right. I'm assuming I have a good chance because I have evidence, however the wait is killing me like everyone else.

So I started my "Fully Developed Claim" 02/08/2019 had my VA Comp and Pen Exam 03/18/2019 . My original completion date was 08/05/2019. Then after my Exam 05/03/2019.

This is my story I've injured both knees, both feet and back while serving In the Army in 2017. progressively my back gave out on me. Now I'm young 25 years, can't work and didn't know about my options until just recently. Lucky for me I was within my year of separation so I got a VSO to work with me and my claim. Still waiting if it's an approval or denial, however today Ebenefits updated status from "Pending of Decision" to "Pending Decision Approval. With a new estimated date 04/30/2019. What happens next. Will I know I'm approved before notification in the mail?

[Preparation for Notification]

I've been in the pending for decision phase for 3 weeks now. My estimated date of completion is May 3, 2019. When should I expect the notification?
