1st pregnancy will be fine but will still get shots. There has to have been a crossover of a positive blood group baby into your system before your body starts to attack a positive baby this can be a miscarriage, birth or abortion that wasnt treated with the anti d. My blood was tested at 10 weeks to see if the babies blood group could be determined it came back that my baby is resus neg also so this preg will be so much less stressful for me don't have to worry about little knocks or tiny bleeds like I had with other 3 preg im so glad the test has come about since my last baby 4yrs ago.
I'm o- as well I started bleeding at 10 weeks and had to get my first rh shot another at 28 weeks & I'll have another at delivery don't stress that's a big thing. With these shots you shouldn't have any problems I'm 31 weeks with a healthy baby girl
u will get a shot from the doc. and ur body will usually reject after u already had child and the pregnancies after will be the ones ur body rejects.
Around week 28 u going to get a shot. I'm 0- to and don't have any problems with that.
