I've been using this app for a few months now, and have been trying to conceive since last month. I was diagnosed with Stage 1 (almost Stage 2) endometriosis in October after a laproscopy. I honestly thought my chances of easily conceiving were virtually nonexistent, but I took three  HPT's today, and all were positive! I just wanted to give some women who may have just been diagnosed a little hope. Each and every one of you battling this disease is a fighter! Don't lose hope...you've survived crippling pain and unforeseen setbacks. Keep fighting the good fight!
