Appointment

So I had an hospital appointment today and I feel like I didn't get any where Jan 2013 I had a miscarriage and I think it was down to the pill I had stopped and got pregnant straight away but then at 8 weeks had a miscarriage and since then we have been trying and nothing and all the doctor was saying was your over weight blah blah I under stand she may suggest losing some weight but to purely blame that when I got pregnant before I find it hard to know when I'm ovulating because my periods are irregular anything between 26 days and 58 days
