Jo,
U got AF symptoms usually? mine quite confusing. But aft 2-3 cycles, I realised that if I get "sweaty" about 1 wk before AF reports (it's my most consistent tell-tale sign), it's likely BFN.
Gritty,
Actually i once noticed that the watsons HPT is produced by Wondo. The watsons HPT cost $8 vs a Wondo branded HPT which I bot from a fellow mother which cost 60 cents! So we land up paying so much more for the plastic casing, the wick, the plastic window, instructions and paper packaging!!! Seriously I cannot understand why OPK and HPT are so expensive in Singapore! Super siao one...
