I googled something...wrong move

So on my birth month board I saw another mom complaining of certain symptoms. She said her dr wanted her to come in because it might be something serious but she was waiting to see if symptoms subsided. But then another person, who is an ER nurse replied that she should go to ER because it could be a serious condition that can hit some women post partum. She mentioned the condition by name. I knew I shouldn't, but I looked it up. I'm not even going to mention the name here to save you from making my mistake. Apparently, this condition can strike anytime after birth up to 5 months later. Affecting 1 in 1300-4000 mothers. I'm trying to tell myself that im not going to get it because I'm healthy. I've never heard of it before and look at all the people having babies and not having this problem. But I know it's going to be in the back of my anxious mind. What do I do?
