I am in day 44 of my cycle and my boobs have not be sore at all so I figured I was just having a weird long cycle. Last month I did not get period till day 39 so I assumed it was the same long cycle as last month. But I tested a couple of days ago and it was positive but thought it was too faint to take seriously and again today  and it's faint but it's definately a line!! I'm 41 and have been trying for a second child for 3 years, success!!
