on april was my first month of pregnancy, i didnt know i was pregnant at that time,
i was just thinking maybe i was delayed because i have mittlesmirz.
on may was the second month of my pregnancy, but i had spots of blood like a menstruation
and thought that i was really not pregnant, but i was wrong because i am pregnant for 2months
the cause of my bleeding was that my husband and i had sex and it made me bleed.
that time i never knew i was rh negative. i found out i was rh negative when i was 6 months pregnant
so i had the shot at 30 weeks...
have i developed antibodies because i didnt had the shot earlier...????????????

I don't believe that should make a difference. I am 0- RH- & had the shots with my son 2x in my pregnancy & 2x after cause his blood mixed with mine (he's 0+) The bleeding in the 1st few months could have been from Placenta Previa (low lying placenta) which is VERY common in early pregnancy, but usually resolves after 13 weeks. OR it could have been from a blood clot caught under the placenta working it's way out. I bled for 5 weeks with my son & he was born healty. I just had a miscarriage at 8 weeks (unrelated to the blood thing) & got another shot. I wouldn't worry too much, but you can always ask your Dr.

I am rh negative also and during both of my pregnancies I received the shot somewhere between 28 and 30 weeks and also after I deliered. I also had spotting with my second pregnancy and had no issues. If you are really concerned check with your doctor. Good luck to you.

you are fine. I had my shot at 29 weeks. I am RH negative. My daughter turned out to be negative so i did not need another shot after delivery.

regarding a previous response i read: both parents do not need to be negative for the child to be negative.

My dad is negative and my mom is postive. Therefore she didn't need the shot.

Hi there. I've had three pregnancies and six shots for being Rh Negative (oh yay). The spotting isn't necessarily from having sex or not having the shot. I bled heavily one day with my first pregnancy for no good reason. And for my third. It's just something that happens sometimes and the doctors didn't have any good reason for it.

And while you might have known you're Rh negative, your doctor did. Your doctor knows your blood type. It's in your records. So s/he'd know if and when you needed the shot. It wasn't up to you to know you were "Rh negative". All that means is you have a negative blood type so your body doesn't have the Rh that positive blood types have. That's what makes blood either positive or negative, the presence or absense of Rh. There's a concern that without the Rh shot, your body would develop antibodies that would attack any future positive blood type babies you might become pregnant with in the future.

You'll also get a shot after the baby's born, either right after delivery or at your six week checkup. I can't remember which it was for me. And every time you get pregnant, you'll have to get the shot to prevent your body from developing antibodies. And also after the baby's born if the baby is a positive blood type. HTH

I'm not a medical expert, but I am an rH negative mother of two. I never had the rH shot until later in my pregnancy- right around when you did. This was what the doctors recommended for me. I knew I was rH negative, as did they. I don't think that you have anything to worry about, but ask your doctor at your next appointment if you are worried. My children turned out perfectly and I'm sure yours will too! Good luck!

Hi I., I read that if your husband is RH negative too, you don't need the shot because the baby will be RH negative.

I'm also rh negative and got the shot about the same time that you did. Your doctor should have checked your blood work for antibodies before giving you the shot, at least mine did. The risk of being exposed to the fetus' blood is only at delivery or if you have a procedure like an amniocentesis or something. They will test the baby's blood after delivery and if he/she is rh positive they will give you another shot at the hospital to protect an rh positive fetus in any future pregnancies. My son was rh negative so I didn't get another shot. I hope that clears up your confusion.

Being rh negative is not something you develop - it's your blood makeup. Both of your parents were rh negative, so it's passed on to you. There's nothing you can do to prevent being rh negative. But it's a good idea to get the shot; otherwise, the baby's father has to have a blood test done to make sure he's rh negative, which can be more expensive than just getting the shot.

They don't give the rH shot until about 28 weeks normally, so I am sure you are fine. They will test the baby at birth and if (s)he is not rh negative then you will get another shot to protect any future babies. Congratulations!!
