Mine turns 7 this weekend. And I never had a normal cycle. So it is posssible. Don't lose hope.
I conceived by charting with
www.tcoyf.com and saliva ferning to help nail down ovulation.
I was on 2000 mg glucophage at the time which helped me get to 60 day cycles. Not anything like regular 30 day, but at least regular 60 day was something I could work with!
I did have gestational diabetes, and I wish I could have gotten lower than the 220 I had gotten to, but I'm satisfied that I was at least LESS than when I started.
I was 28 too.
So def don't lose hope!
GL!
