Undercooked potatos

I couldn't get my potatos to fully cook in a caserole. I ate some bc it wasn't bad. Then i googled it and one place said undercooked potatoes and safe and another said they weren't. Are undercooked potatos unsafe for my pregnancy?? They were slided and in the oven 60 min. I hope nothing bad happens? I was trying not to be paranoid this pregnancy. Then it turnsout everything seems unsafe after all. Sigh.
