Congratulations on losing the 10kgs to start! Great work!
I weighed far more than you when I got pregnant, close to 120kg (I feel sick just writing that down) and I had a very healthy pregnancy with minimal weight gain and maintained healthy blood pressure and acceptable GTT results throughout.
However, I wish I had done something about my weight before pregnancy like you are. My Ob said I could greatly reduce a number of risk factors if I was in a healthy weight range.
Just wanted to wish you feel for your weight loss journey before pregnancy and to offer encouragement to keep going!
If you do fall pregnant before losing more weight, make sure you get a referral to a dietician to help you manage your pregnancy weight gain and diet during pregnancy to support you and growing bub as well as possible
