Hello jennifer,
dont worry. I really do not know your complete sex history however just get relieved that you are not infected. Dont get carried away by words. Know what you are doing and if its right, just throw away your worries.
Anyway, if you have taken a test possibly after a 3 month window after your possible exposure, you dont have to worry at all. You, your hubby and your baby are just fine. If not, you have not taken a conclusive test after the 3 month period, still though nothing to worry about, you can encourage yourself for a conclusive test jus to get things off your mind.
I will pray for you, that you have a wonderful baby and a nice married life.
God bless and regards
