I'm in a funny situation. dh and I are trying for number 2 but I'm still feeding 10mo ds1. Meaning I've had no periods so don't know when I'm due on. 
for the last few weeks I've been having the same symptoms I had with ds1, even down to leg cramps. did a cheaply test last week as I was convinced but it was a no. is it worth buying a clear blue or is a no a no?
