Hashimoto's Disease - do I need an Endocrinologist?

I found out last week that I have hypothyroidism, when blood tests showed my TSH at 16.64.  My T4 levels were at 9 I believe, so normal, but towards the lower end.  A repeat test confirmed these results, and my doctor also went ahead and tested for the TPO antibody and the thyroglobulin antibody.  My TPO came back at >600 and my thyroglobulin antibody was at 234.   My doctor told me because of these results I have Hashimoto's thyroidism.  

What I'm curious about is whether I should see an endocrinologist?  My PCP seems comfortable handling this, but I wanted to get an opinion from others.  

There is something else to add to the mix.  My husband and I are planning a frozen embryo transfer on 4/19.  I'm not sure how this will affect that, or if I should delay it. I'm waiting to hear from the reproductive endocrinologist on that.  I've been on 50 mcg of Levothyroxine for about a week.
