No you should not feel guilty; you should do what feels best for you. When i was pregnant i had no desire at all either; so i didnt. Same thing with my sister in law. I have heard about better bonding with your baby; etc. But i wont say i believe thats completly true. My daughters now 7 and very healthy; we have a very close relationship. So; dont be intimidated by "all the hype" you hear; its for some women; and some- not. Do what ever decision you feel most comfortable with:)
