Pregnant body insecurities.

I love my wife and I let her know that alot. Now that she is pregnant I feel that the insecurities about her body have begun. I feel bad for her when she feels a certain way about her body. I try to encourage her and tell her how sexy she looks and still caress and massage her and engage in intercourse as much as possible. I feel as she gets bigger its gonna get worse for her insecurities. I think shes hot and she gonna look great pregnant but this roller coaster of emotions and insecurities is gonna be a hell of a ride. Any kind of advice?
