Rhesus Negative

Paige
Hey ladies! 
This is my first baby and I'm 14+1, due on October 10th.
We had our first scan and blood test on April 4th and I received a letter on Saturday to say I'm Rhesus Negative and will need injections.
I've read up about it and it seems pretty scary 😨 Has anyone else been through this? I would love to speak to others who have some experience with this!! X
