Starting weight between 51 and 53kgs for all my pregnancies.
All pregnancies except the last I gained the most in the third trimester.
Last pregnancy I gained half the weight I put on by 16 weeks. My other pregnancies I didn't even start gaining weight until I was nearly halfway.
I lost it all within except two kilos within a week with each pregnancy. Those 2kg I held on to until I stopped breastfeeding, except my last...I never actually lost it (and several years on am now heavier again...but still wearing size 8 clothes. Different body shape and more muscle now. I'm happier with my body now, at 58kg than I was at 51-53kg).
