Thank you appreciate the get back but as i said i heard that it didnt make sense so i had to ask
Just don't blow in her vagina especially if there is a possibility that she is pregnant. It could cause a lot of problems and hurt mom and baby
You are fine. Even if saliva did kill sperm cells it would be virtually impossible for you to get it far enough in there to even effect the sperm or egg. I have also never heard that oral sex is any problem during pregnancy. If your really worried ask her ob/gyn but honestly I think you are fine. Enjoy!
