Rhysus negative

[Holiday16]

Hi all, had my first midwife appointment today and all went fine until I got home
And my partner told me he thinks he's rhysus negative blood group.
Is this something that I need to urgently tell the midwife or can it wait until my next midwife appointment at 16 weeks? I'm currently 9 weeks

I'm not sure if it affects the pregnancy or not thanks in advance x

It can wait until your next appointment unless you have any blood loss. Congratulations

Your partner (maybe) being Rhesus negative is not that important. It's what you are that matters, which they'll have tested for in your booking bloods. No need to panic call the midwife!

If you're negative then you will probably need anti-D injections; if your partner is also negative then these technically might not be needed but they're still recommended as people often aren't totally sure about their blood group and/or the father of the baby (not saying this is the case for you, but it's more common than many realise!). If you're positive then nothing extra needs doing.

It's only an issue if you were rhesus negative and he was rhesus positive

Hello I am Rhesus negative and pg with my third dc. All with no issues and you just get a jab about 28 weeks and then one after you had the babies. It’s your blood that’s important tho not the fathers

Thankyou all. My blood group is 0- I believe. But is being double checked as we speak - glad it won't be an issue
Thankyou again

Doesn't matter at all what your partner's blood type is, only yours. His being negative would actually be good news if you also were because it would remove the possibility of rhesus disease. Your blood will be routinely checked and your midwife will let you know if you happen to be rhesus negative.

I got told my blood group when I saw the midwife for the chat about screening tests after my 12 week scan so not long to wait if your trust does that too OP.

Wish my partner was negative! If you are negative, and your partner is positive, you will be offered an injection around 30 weeks and again after birth. No big deal but it does sting a bit. You may also need this if you have a bleed or fall over during pregnancy. If your partner is definitely negative and definitely the father, you won’t need this injection. In some places they now test the baby’s blood type - mine was positive, so I needed the injection.

Nothing to worry about :)

If you are rhesus positive, you have the D antigen on your red blood cells - nothing need to be done.

If you (the mother) are rhesus negative, you don't have the D antigen on your red blood cells. IF you are rhesus negative AND carrying a rhesus positive baby (meaning the baby's father is rhesus positive) AND your blood mixes with baby's, your immune system will react to baby's D antigen and produce antibodies. It's not harmful for your first baby but if you are sensitised then go on to have another baby, the antibodies could cross the placenta and attack the second baby's blood cells. You would be offered anti-D injections to guard against the antibodies. You wouldn't necessarily become sensitised either.

So if your partner is rhesus negative, there's nothing to worry about.

If both you and your partner are rhesus negative then your children will also be rhesus negative as they would need at least one of you to be rhesus positive to pass on the positive factor. Therefore, as he is rhesus negative, as are you, you will not need anti-D because the baby will automatically be negative too.

Hi all - just checked as I am a regular blood donor and I am O+
I will just mention it at my next appointment as it may mean I need the injection but obviously I have a long time until 30 weeks thankyou for putting my mind at rest x

If you're 0+ you won't need an injection. It's only for rhesus negative women.

@Holiday16 as pp said only Rh neg women need the anti-d. Rh pos women can carry Rh neg or pos babies with no trouble, so it won't matter if she turns out to be Rh neg - you won't need anti-d.

Thankyou so much ladies
