Just found out I'm Rh Negative 😔

Anna • Waiting patiently for Anna'Sophia👶💕💜👪 😊 Due October 31st 2015 💜💕
I am 22 weeks pregnant & I barely got told that I am Rh Negative. Now one more thing to worry about :( Im stressing so much about it now . Are any of you Rh Negative? How was your experience while being pregnant? Should I be super worried ? Help ! 😢
