blood type

Soo the midwife infirmed me that I'm O-negative which means my blood can't pass thru to the babies blood and if it does it can cause my cells to fight against the baby??? She sed I have to have an injection at 28 weeks regardless but if I bang my belly or fall over or anything then I have 48 hours to have this injection before it can cause harm??? Has anyone else ever heard of this???

Yes because I'm A neg. However,the shot is for future pregnancies to prevent miscarriage. You and your baby now are fine.

That's not what the midwife said to me she said I have to have the shot at 28 weeks in case there's complications in labour?? I dunno I'm no professional it just freaked me out abit knowing if I bump myself or fall my little ones at risk

Actually babies blood can't pass through to yours which can happen during labor or if you fall and injure yourself.  If your body senses babies blood and they have a positive blood type your body will try to get rid off the foreign body, the shot prevents this from happening.   You and baby are fine now just be careful and they usually give the shot at 28 weeks.  Luckily both my husband and I are positive.  My mom was negative so she had to go through this with me.

I am O- also.  It is not a big deal. I got the shot while pregnant and possibly another after I had my son. I never had any issues. I wouldn't worry about getting hurt because I'm sure you are already being careful.  But if you do get injured,  just make sure to inform your doctor. O- it's not a bad thing... we are actually universal donors.  Blood banks like our blood because they use it for premature babies since no blood type will reject it. The downfall of course is that we are only able to receive O- blood.

You will receive the shot at around 28 weeks as well as at least one after delivery, depending on baby's blood type.   It can occur during labor or any abdominal trauma where baby's blood can come into contact with mom's.  When This happens, if baby has a "positive" blood type, mom will form antibodies against that blood type (without the shot). If this is the case, generally it will not cause issues with the current pregnancy, but with future pregnancies.  This is because the antibody takes time to develope. Please don't worry over it... It really is very routine.

Your midwife doesn't quite know what she talking about. All the women in my family are A negative so we have to get the shot at 28 weeks, but the shot is for future pregnancies. Your fine.
