Problems with the Rh factor happen when the mother's Rh factor is negative and the baby's is positive. If the father's genes are -, and the mother's are -, the baby will be: If the father's genes are -, and the mother's are + -, the baby can be If the father's genes are + - Rh-positive, and the mother's are + - Rh-positive, the baby can be: If a father's Rh factor genes are + +, and the mother's are -, the baby will have one + from the father and one - gene from the mother. If a father's Rh factor genes are + +, and the mother's are + +, the baby will have one + from the father and one + gene from the mother. More specifically, consider the following: If a person has the genes -, the Rh factor will be negative.Ī baby receives one gene from the father and one from the mother. If a person has the genes + -, the Rh factor will also be positive. If a person has the genes + +, the Rh factor in the blood will be positive. The Rh-positive gene is dominant (stronger) and, even when paired with an Rh-negative gene, the positive gene takes over: Rh factors follow a common pattern of genetic inheritance. A baby may have the blood type and Rh factor of either parent or a combination of both parents. The following are the possible combinations of blood types with the Rh factors: If there is no Rh factor protein, the person is Rh- negative. If the Rh factor protein is on the cells, the person is Rh-positive. The Rh factor is a protein that is found on the covering of the red blood cells.

My 1st baby was born at 41 weeks, had anti d at 28 and 33 weeks and following the birth, my 2nd baby was born at 40+16 very late baby huge too, anti d given also at 28 and 33 weeks, and not after delivery for some reason not sure of the reason why, and my 3rd baby born 7 weeks was born at 39 weeks via c-section due to the cord being wrapped around his neck, i had several anti d injections, one at 19 weeks due to a kid running into me, double dose at 25 weeks due to the dog jumping onto me, and a triple dose at 28 weeks which is normal as they don't do them at 33 weeks anymore, they are all just a precauction and nothing to be alarmed about.ĭon't worry about it all, i also read many horror stories on the net but sometimes i think you can worry yourself silly after reading things on here, but honestly all my babies were fine never had any problems at all and are all doing fine.Įnjoy your growing bump and before long you will have a little bundle in your arms xx圎very person has a blood type (O, A, B, or AB) and an Rh factor, either positive or negative. I would like to point out that being Rh -, isn't such a bad thing, i too am Rh- and i've just had my 3rd baby, the first pregnancy is fine and the anti d injections is to prevent a blood crossing over and affecting future babies! Massive congtratulations on your pregnancy, what exciting times ahead for you. Thanks so much for reading this, any advice greatly appreciated I think I understand the basics of it all but I can't seem to grasp how serious/common this is from what I'm reading, some sites give really terrifying examples of babies needing blood transfusions after birth etc.Ī) once i have the anti D injections in the 3rd trimester, will this mean nothing can go wrong, or is there still a risk to my baby?ī) how common is in for the mothers blood and baby's blood to mix and is there anything I can do to prevent this?Ĭ) what are the odds that this won't affect my baby at all? My midwife, while lovely, does seem to rush through explaining things - I have since looked on the internet for a bit more info on all of this and really have got myself worked up about it. I had my 16 wk midwife check up on Friday, where I discovered from bloods taken at the first mw appointment that my blood type is O negative, and therefore there is a risk to me and my baby if our bloods mix and I need to have 'anti D injections'. I am 27 years old, 16 weeks pregnant with my first baby.
