You will be fine.. just do research! ..Like both sides of each story, and the pros and cons to each topic.. freaking out is what will raise your stress levels... and then you will really be freaked out then because you can lose your baby when you're too stressed. Good luck!!
Just be calm and think as positive as possible. I had the same worries and still have some. Like I said try to stay positive not stress eat healthy and take care(:
