Health Conscious?

I would not say I am very health conscious. Else I would not have been so overweight. I am 5'2" tall and almost 90KG. I guess a lot has to do with my pregnancy and my post delivery diet. But even before my pregnancy I was around 75KG which is on the higher side. I used to go for walks, perform light exercises and yoga before but ever since getting pregnant I have totally quit on everything. Even my eating habits have changed as the diet I have needs to be high calorie diet so that the baby feeding on me gets all the necessary nutrients to grow well. But I am planning to start with my light exercises and yoga soon so that my weight doesn't get out of control. I am trying to find out the right exercise routine that I can follow so that it doesn't affect me or my kid in a negative way.

I am not much health conscious. Thoug I feel I should be , I am not that much conscious. Sometimes I feel that what for we should be much health conscious. The answer is not availabe to me
