Why I'm I not feeling a bond with my baby...I feel so guilty :(?

I'm sure it's because of your previous losses. I'm sorry you had to go through that. Subconsciously you probably don't want to get emotionally attached to this baby yet because of that. I'm sure that's also the source of your paranoia. You should seek counseling to help you deal with your emotional troubles. Again, I'm sorry for your loss and I wish you all the best with this pregnancy.
