I'm married for two years.And now we are planning out a child.And from that day onwards I've stopped exercising at all even though I'm not pregnant in the fear that I will not get pregnant if I exercise.I was a little overweight but in good shape but after I have stopped I have gained lots of weight. I used to weigh 60kgs and now it is 70 kgs.I used to work in treadmill and stepper.Please advise me what to do as I've become depressed?
