Disappointment with every period.

Along with tender breasts, bad cramps and bloating I now have a major feeling of disappointment every time I get my period. :( 
​I miscarried months ago and have been trying again as soon as we were advised to after, but I have a very irregular cycle so makes it more difficult. Last few months cycles were 27 days /35 /32 /26.  Any advise or similar situations?
