I wasn't a member until I read your note.
I was married the first time in 1984, by then we knew I wasn't going to get pregnant easily, Well to make a long story short, PCOS, Clomid....
October 16, 1985 - I had a beautiful daughter, Jazmine. Fast forward to 1992 New hubby, new life, We wanted to add to our family, back to Clomid, no luck, over and over again, after 4 years of trying we figured we were only meant to have the one child and decided to be happy with what we had.
Then when my Daughter was 17 she blessed us with a Granddaughter,Abigail, she came a little early in her mother's life, but we love her just the same.
My Husband blames (or thanks) our Granddaughter for our Miracle, but I know it was 3 months on the Atkins diet that lead to my becoming pregnant at 39 years old.
I had just lost 30 pounds was looking fine and feeling great, buying new "skinny" clothes, after 3 days of flu-like symptoms, I took a pregnancy test in jest.
It took the majority of my pregnancy for the shock to wear off, but now our little miracle, Desirae, is 9 months old, and the apple of our eyes.
My new motto in life is : Never say Never.
So my answer to you, dear, is Yes, low carb diets + PCOS = Baby !!!!
So keep tying and try not to stress too much, stress seems to slow things down.
