I don't even know you but im so excited for you. I've always used cheapy tests (10 off ebay for about £2) or they sell them in the poundshop. All the same except the fancy packaging, they have to pass all the British safety tests etc to be able to be sold so you can be assured that they will tell you the truth. For me personally, clearblue, espec the digi ones were pants!.
Ohhhh good luck!! xx
