Fears and anxiety

I feel like I have more fear and anxiety now than I did when I was still in the first trimester. I’ll be 16 weeks tomorrow and I’ve been having some cramps and pains. I’ve spoken with my doctors office who isn’t worried and told me at this point in pregnancy that’s all normal with all the stretching and growing but I’m just having so much worry and anxiety. I don’t have any appointment until next Friday for my next Routine appointment and I’m just so scared of getting bad news. I hoped this constant fear would go away once the first trimester was over but I can’t kick it.
