I ovulated on the 1st, the 9th I'm going under anesthesia for a colonoscopy, if I'm pregnant is it to soon for the anesthesia to affect to fetus?

Pregnancy. If you are pregnant, short of a serious bleeding emergency, a colonoscopy is not a good idea.
No, not too early. If there is a chance you might be pregnant, I would not go under anesthesia. Why take the chance and even think about it unless the colonoscopy is essential.
