VBA: Wait until browser loads more than once - vba

Question

I've been working on a program to fill up a form after the webpage is loaded, its working well with this:
Do
Loop Until MyBrowser.readyState = READYSTATE_COMPLETE
After this my code loads, fills up the form and the click the log in button.
Here comes the problem, i've been trying to click a button right after the new page loads, so i tried the same loop method to accomplish this, but it is not working.
I said to myself, this can't be, it has to work!, so i tried making a code for a search on youtube and for my surprise it did work, it searched a video and then i could select the one i wanted.
So if it does work, why it doesnt with my login page?
I noticed the page does not reach the next page right away after logging in, it loads a page and then quickly it loads another one and reroutes to that one.
Do you have any idea how to wait until the browser reaches that point?
whole code until now:
Private Sub CommandButton3_Click()
Dim HTMLDoc As HTMLDocument
Dim MyBrowser As InternetExplorer
Dim MyHTML_Element As IHTMLElement
Dim MyURL As String
On Error GoTo Err_Clear
MyURL = "url"
Set MyBrowser = New InternetExplorer
MyBrowser.Silent = True
MyBrowser.navigate MyURL
MyBrowser.Visible = True
Do
Loop Until MyBrowser.readyState = READYSTATE_COMPLETE
Set HTMLDoc = MyBrowser.document
HTMLDoc.all.user.Value = "user"
HTMLDoc.all.pass.Value = "pass"
For Each MyHTML_Element In HTMLDoc.getElementsByTagName("img")
If MyHTML_Element.getAttribute("src") = "url" Then MyHTML_Element.Click: Exit For
Next
Set MyBrowser.document = HTMLDoc
Do
Loop Until MyBrowser.readyState = READYSTATE_COMPLETE
Set HTMLDoc = MyBrowser.document
For Each MyHTML_Element In HTMLDoc.getElementsByTagName("img")
If MyHTML_Element.getAttribute("name") = "name" Then MyHTML_Element.Click: Exit For
Next
Err_Clear:
If Err <> 0 Then
Err.Clear
Resume Next
End If
End Sub
