Is this it?

Yesterday on CD 5 I got a positive opk and although I had been bleeding for 4 days (right in line with when I should have my period) it has been very light and brown and I have had no period symptoms my cramps usually get really bad, so I took a pg test this morning and got this - is this it ladies? Should I do my clearblue now? The pics from top to bottom are of the same test - straight away, at 3 mins and at ten mins
