Cautiously optimistic!

After 1.5 years of ttc, I finally got my bfp. I'm still in shock. I'm going to my doctor on Monday to get a blood test done to confirm. I'm happy but also anxious. It really is a balance to stay grounded so early in the game as I know things can go wrong. I am hopeful but also realistic. Is it anxiety provoking right until babe arrives? I think I've known so much loss around me from other women's experiences that it's made me more anxious and careful than if like to be. Any words of wisdom?
