Messed up cycle following MC D&C

Jerri • 1DD aged 2 TTC following MC D&C
We have been trying for 2 years for #2 we fell pregnant November 2014 but sadly ended in MC. Since then my cycle is all over the place apparently I'm ovulating about 4/5 days before my period and the doctors keep putting me off as they said im only 23 I've got loads of time! I feel completely lost!! Any advice from you lovely ladies?
