Durian's, local fruits!

Is it okay to eat durian for pregnant women? My husband is Sabahan people. Durian? some of local fruits in Sabah that's famous and one of Sabahan favourite fruit's! Even tho it smells but it tastes good! So can or not? My mother-in-law said, the pregnant woman can eat durian's but cannot eat too much. I'm confused cause it's too really yummy.
