Clomid/ infertility

In September I started clomid got pregnant in October and found out a week before Thanksgiving..a week later my pregnancy was found to be ectopic. I got methotrexate shots to end the pregnancy. Hardest couple months of my life. Fast forward a little to today..and today is my last day on my first round of clomid and I'm terrified that if I do get pregnant it might turn out the same. Such a scary thought! I believe in my heart that everything will be fine but still in the back of my mind I worry.
