I've been trying for a year to get pregnant. In that time I've had ine miscarriage but not managed to get pregnant since. Last month i had a blood test which confirmed all my hormones are un sync. Im normally as regular as clock work and use s app to track period and ovulation. Im now 7 days late i tested yesterday but got a negative result. I sm 41 do you think its the start of the change?? But i would of thought my blood test would of highlighted this last month. 
Im not stressed or anything so can not understand whats going on any advise would be greatly received. One last point my boobs do hurt a little at times and get some cramps now snd then
