Exercise during pregnancy

Erm, though exercise is crucial, I value safety aspect more (as i had a threatened miscarriage) so I only go for walks more actively during 2nd and last trimester when baby was more stable. Few days prior to EDD, I followed YouTube to do some exercise as I din want to be induced. Took longer walks and did abit of squarts and stretching to the best of my abilities (cuz it's very taxing to exercise with that big bulky tummy la).
