more specific answer ask the doc

STDs can be passed from a pregnant woman to the baby before, during, or after the baby's birth. Some STDs (like syphilis) cross the placenta and infect the baby while it is in the uterus (womb). Other STDs (like gonorrhea, chlamydia, hepatitis B, and genital herpes) can be transmitted from the mother to the baby during delivery as the baby passes through the birth canal. HIV can cross the placenta during pregnancy, infect the baby during the birth process, and unlike most other STDs, can infect the baby through breastfeeding.

The harmful effects of STDs in babies may include stillbirth (a baby that is born dead), low birth weight (less than five pounds), conjunctivitis (eye infection), pneumonia, neonatal sepsis (infection in the baby's blood stream), neurologic damage (such as brain damage or lack of coordination in body movements), blindness, deafness, acute hepatitis, meningitis, chronic liver disease, and cirrhosis. Some of these problems can be prevented if the mother receives routine prenatal care, which includes screening tests for STDs starting early in pregnancy and repeated close to delivery, if necessary. Other problems can be treated if the infection is found at birth.

Yes, there is a possiblity that a neonate could have abnormalitites if the mother has an STD. Whether or not there will be abnormalities and what those abnormalities may be depends on the STD, which you have not mentioned.

IT IS POSSIBLE HIV CAN BE PASSED FROM MOTHER TO FETUS i BELIEVE SYPHILIS CAN; THAT IS WHY MD'S TEST PREGNANT FEMALES FOR IT

if you give birth while you have an untreated std, then yes, this can affect your unborn baby. most std"s are treatable. Go to your doctor to be checked.
