Infertility is such an up and down road and the hormones that swing don't help at all.
However, in my case clomid helped me to have 3 children (one singleton and one set of twins). It was worth it for me and I hope it is worth it for you.
The low carbs help too. I could get pregnant on my own by eatting low carbs but those pregancies all ended in m/c. I needed clomid to have a healthier egg.
