What is the correctly punctuated version of this sentence?
When my doctor prescribed Clomid 10 mg a few months back, I did not believe a dose so low would work for me. But evidently I had some medical issues that would have prevented me from avoiding serious side effects if I had taken a higher dose, so I had to trust the expertise of my doctor. I am happy to tell you that I recently got great news - I'm three months pregnant, so it works after all, plus I was able to keep taking my other meds.
