My husband and i are not having at all..I'm 8 months pregnant. is this normal?

Before i got pregnant, my husband and i would have about once a week or thrice a month. I know and i can feel that he loves me so much. I just don't feel its normal.. is it possible that i have higher drive than him? when i was in my 2nd trimester, we seldom do it. right now im in my 8 month and we're not doing it at all... is this normal?
