hI There Ash, Welcome on here.
What is TTC? Please do not stress yourself if you cannot run, by all means, get out here and walk the whole thing. You are moving and that is all that matters. Nutrition plays a big factor too, so watch what you eat too. A lot of us are on MyFitnessPal and we encourage each other there too. My name on there is kellybarr1. I track everyday usually. You can do it, so get out and go. We are all here helping each other. HUGS!
