Surgery, miscarriage, another surgery.

I had an emergency appendectomy in March. When I went in to the ER I found out I was pregnant. My husband and I definitely didn't plan it, we had an 11 month old (now 12 months) and never really wanted another child. Our first baby wasn't planned either. I was upset about the second pregnancy at first, then we got excited. Two weeks after surgery, I started bleeding. The ER told me it was "normal" and didn't have an OB see me. I knew something was wrong because I was having labor pains. :/ A week later they finally scheduled a D&C (after which they told me I had already basically passed everything) so two surgeries later I'm still recovering. Grief didn't hit me hard, until now. I feel guilty for having the first surgery since that's more than likely what caused the miscarriage. I know I would've had my hands full, but I was very excited.
