Rhesus negative blood

Hi y'all!
Are any other pregnant ladies RH neg? Have you had the test to find out what blood type your baby is? If it was positive how are you getting on?
I am RH neg and 13 weeks today, so won't know the blood type of my baby for another 2-3 months and I feel very anxious about it.
Really, I just need to know what may happen and how it's been for you guys :)
