That's the main road in front of my place! there are a few Punggol/Sengkang mummies who are starting pre-natal with me in Nov, let me know if you are interested and I'll add you in the group convo. Cheers!
If you have never done yoga before it is best to start only in 2nd trimester, but if you are quite regular or have always been active pre-pregnancy (exercise twice a week at least) then you can start as long as you feel comfortable and up for it :)
