Good fruits?

I ate almost all kind of fruits including durian and pineapple cuz my TCM recommended one to two slice of pineapple in a month to ensure the amniotic fluid is sufficient. but everything need to be taken in moderation. after my 4th month, I stop taking fruits with high sugar level since Dr diagnose me with mild gestational diabetic and dietitian also told me to stop taking fruits like watermelon, banana, durian etc. I'm on my 30th week now and I'm taking only guava, apple and honeydew on a daily basis. so far fetus weight maintain at 1.2kg this week and I only gained less than 2kg for the past 30 weeks
