@meistet44,
There's no way of anyone here giving any meaningful answer. Just because you did not ejaculate, that doesn't mean your still couldn't make her pregnant. In pre-cum some sperm are present. Your story is a bit confusing why you two were engaged in sex 24 hrs after this alleged rape incident with husband.
Clearly, she needs to take a pregnancy test to see if she is pregnant. Then, if she is pregnant...after the baby is born, a paternity test would be needed to determine who the father is.
