Ramadhan Month - Should I fast or not?

I fasted during my pregnancy. I was in my 2nd trimester that point of time and working as a preschool teacher. For me I managed to keep my fast the whole day as I was busy and didn't really feel the need to eat or drink. But concerned people asked me not to fast. So I didn't fast once a week to keep them feel better. Because to me if you feel that you can do it then do so. But of course don't be too drastic until something bad happens.
