Firstly congratulations!
I'm RH neg and my OH is RH+ and i've just had my third baby. As long as you had the anti d last time after the birth there shouldn't be any problems.
It might differ in different areas but i think you have the routine anti d at 28-30 weeks and again after the birth.
If you get any bleeding or have any knocks to bump you will need to ring doc or MW asap to have another anti d injection within 72 hours of bleed.
