I am really confused what is happening to my body even my last period flow was less . I am 32 gonna be 33 next month . I have a regular 28 cycle and have been ttc for 15 months . As i am already depressed for unable to conceive on top  of that my CM also dry . Last cycle was ok but i couldnt have ewcm . But this cycle no or less Cm .
