wow im so confused so many different answers...i find it wierd that every vet has differently believes on the matter...since some recommened use of products and others dont i figured the safest thing to do is to call the vet and see what to do...since the doc was in surgery she told me to call back at 4...but strongly spoke against any meds...she said as far as she knows the vet is against using medication during pregnancy...but i do NOT wantt her to suffer with fleas and whatever they are carrying so im just going to call back to ensure the health of my baby and her babies...thank you all for the great posts
