Hi everyone. 
Just after a bit of advice please. 
So last night my hubby bought me a twin pack of the clear blue digitals. 
I did one as soon as he was back and it showed pregnant 1-2 weeks. 
Stupid me I decided to do another about two hours later don't know why I did it but it obvs showed not pregnant. 
My hubby then bought me one for this morning when I woke up. Lol. 
I did that one and then it said not pregnant. I was gutted. 
Still feeling a bit strange I thought I'd pick up a couple from our local chemist. The pharmacist said they are okay. They are called Freedom. 
So I did one at about 4pm today and then another about 5.30pm. 
These are the photos. 
So what do I believe?? My period is due either today or tomorrow xxxx
