hi, Thank you for consulting with Health Care Magic, and i understand your query. To gain around 10-12 kg s during pregnancy is normal, and is considered to be good for the delivery of a healthy baby. But by your query i understand that you have gained a lot over the pregnancy period, and Utrogestan could be a cause for your weight gain since it is a progesterone hormone pill. 3 c-section and a abortion is quite something, i suggest you to consider family planning as it is too riskier for another c-section. About your weight issues talk to your gynaecologist about discontinuing your pill and as of now go slow on the dieting as your baby needs nutrition from the breast milk. once you stop feeding , you can start dieting and including moderate exercises to reduce weight. Hope this helps, get back to me if you have further queries. Wish you good health. Take care.
