To test or not to test?!!

Hello ladies...

My hubby and I have been TTC for nearly a year - had a chemical miscarriage in August..

I am 12 Dpo - for the last week I've had sore boobs, been overly emotional (v grouchy!) and generally feel a bit funny..

My cycles have been all over the place (28 days/32 days/34 days etc) so although glow says AF is due 27th I don't know..

I'd love to get a BFP this Xmas and don't know if I can face heartache of a BFN xx
