I do not have those antibodies - but I can tell you that even if you have high levels of antibodies it still doesn't mean that there is a high chance your baby will be affected by them. I think the rate of heart block and neonatal lupus is less than 2% on average across these studies. I assume you are under the care of a OB-gyn, and your baby will be monitored closely and looking for any evidence of heartblock through ultrasounds later on in your pregnancy.
We have had a few mothers go through pregnancy with these antibodies, but response rates are slow being close the the holidays so you may want to check back later and see if anyone has stopped by to respond in person about their experience. There are also a few threads in the Pediatric forum on our website about babies with neonatal lupus from these antibodies.
Here's one link that should be reassuring to you about a good quality study done on the topic of pregnancy and SSA antibodies...

Good luck to you and I hope you can come back and let us know when you've had your baby and he/she is safely in your arms.
