I got another cat about 6 weeks ago and as soon as I got her, I went and got her vaccinated. Then I had to wait 3 weeks and I got her vaccinated again. Finally I was able to make her an appt to get spayed, but it's not until may 15 and her kittens would most likely be delivered by then.... I called and they said they will see her early and spay and terminate the pregnancy. She is probably about 6 weeks along, so what are the potential side effects? I'm just worrried it will do more harm than good.
