Newby needing advice...

[MLR1901]

Hi all,
Firstly this forum has saved my sainty for the last 10 days, as I am new to this whole TWW and TTCing!
And reading your thoughts, advice and stories has assured me so far heaps...
So I thought I will see if anyone can shed light on my situation..

Ok so DH (32) and I (31)
I have/had CIN3 and two laser treatments for this - so far still showing as CIN3 but low grade and keeping in check...

anyways...
it is our first month of TTC but not really trying..
My cycle is usually 31-33 days..
I can feel when I ovulate and from which side...
My last AF was 2nd Dec...for 3 days (normal)

I ovulated approx 20th Dec - DTD same night

so leads me to now...
I felt like I was getting AF syptoms approx 8-9 days ago - not due till 4th Jan so quite early for me to get these syptoms...
My friends (with bubbas) keep telling me to wait till I miss AF to check
I have done 3 HPT
one at 9dpo
one at 10 dpo
one at 11dpo

all BFP...
but I'm still due for AF
I have pregancy symptoms... I think..

do i wait till AF doesn't arrive and if so how long do I wait?
Or just go to GP and ask for HCG blood test??

thanks in advance...
