Ttc more problems then i thought

Bianca • Me and my best friend got married March 15,2014 and now we are ready to start our family together after almost a year of us being married
OK me and my husband are TTC and for to months now my body has been going crazy and I've been having my cycle every other week my doctor said that its shouldn't be happening but then he tells me my body is normal and he can't find anything wrong I don't know what to do I'm going crazy and of course crying myself to sleep isn't helping has anybody gone through this before???
