Anti D injection needed?

Hi, I’m here again just to ask another question.
I had a letter from the hospital today that I’m B negative so I’ll need the Anti D injection just incase baby is a positive blood type.
We found out today too that my partner has a negative blood type he’s A-, I’ve asked my midwife then what will happen, she said she’s not sure what that means if the baby will have negative blood too. So I’ve looked it up and I’ve seen some places say that baby will only have negative blood because both parents are negative but I’ve seen sites saying that the father or mother could carry a positive gene in the blood such as A-+ so baby might actually be positive because positive always beats the negative. But on my letter it just says B- and his card says A- we don’t have A — or B— or even A-+ and B-+ so I don’t know if I carry a positive gene and my partner doesn’t either! And in wales they don’t offer the blood test or your blood to see what baby’s blood type is which makes so much sense so I don’t know why they don’t because they do in England, but if I still have the Anti D injection at 28 weeks and baby is negative will that harm the baby having this injection?
Sorry that’s a lot just want some insight and help from someone that has been through this! Thanks :)

If you are both negative then the baby will be negative. Most trusts will still advise you to have the injection though, due to the odd few cases where the partner actually doesn’t turn out to be the father of the baby!! (Obviously not in your case) but just a heads up if they advise you to still have it, it’s just a safety net! I had it and it was fine, a little sore and no adverse affects my partner was + and my daughter too so no avoiding it for me!😂

That's right, 2 negative parents can not produce a positive baby because you only carry the negative genes.

A- can be either A- & A- OR A- & O-
B- can be either B- & B- OR B- & O-

O is recessive to A & B but if your baby gets A- & B- it will present as AB-

More combinations for the positives.

@JumperooSue ahh brill, this has out my mind at rest! Oh god haha, that does makes sense though! Yeah that’s very true! I’m glad it didn’t hurt or anything!
@Chelyanne thank you so much, I’ve been well and truly educated today! Haha
So baby will be negative then, I’m just a bit worried would it harm the baby if baby is negative and it’s not needed if that makes sense! Might just be me being silly!

It will not do baby any harm at all.
We have 5 healthy kids and I had it in all 4 of those pregnancies, already booked in for it with current one too.

Good luck and enjoy Smile
