I've been having these horrible headaches and dizziness as soon I reached 2nd trimester. Yesterday I woke up with an extremely sore neck and back, so I took some Tylenol since everyone says its safe. And without thinking about it I put icy hot on once in the afternoon then right before I went to bed, and only after did I think "oops am I supposed to be using this" its hard to remember I now have so many restrictions... from what I looked up on Google some woman said their doctors said it was okay and some said it wasn't. I will not use it again, but will my baby be okay from using it twice yesterday?
