i was running every single day for 1 year plus... at least 4km..some days 10km+, a few occasions 24km.. so I thought that I can run as when u Google they say that if you are actively running you can contd to run during pregnancy. my gynae did advise not to during first trimester. I didn't follow his advice because I thought I was super active before pregnancy and thought that I can continue. but I was wrong as I had a miscarriage at week 10. although they didn't say that the reason was due to running. i am pregnant again after a few months and totally avoid any strenuous exercises.. only walking now.. currently going week 30...I suggest that better listen to your gynae so that there will be no regrets
