Hi,
I have bought a pack of fertility tests to try and work out when I am fertile. I have only had 2 periods since having my DS. The gap between them was 38 days (yikes I know!). Anyway according to the instructions the packet says for 38 days you don't need to start testing till around day 21 - hmmm that seems a bit late for me.
As I have only had one 'gap' between periods so far I am not sure when to start!
