I am so sorry for your loss! I miscarried on the 19th December 2009! Different women react differently in terms of their bodies! My legs were hurting after the D&C really badly! so my obgyn told me I am lacking calcium so drank a lot of milk! as for the weight gain that too happened to me! I only gained like 3 pounds in my 14 weeks of pregnancy but after my miscarriage I gained like 9 pounds! our bodies react differently even though we all have the same parts...I would suggest you contact your doc...one thing I have learnt is that you have to stand strong against doctors and if one does not give you the correct answers or attention you find another one! don't be left unsatisfied and keep bothering the doctors for answers and tests. I made the mistake of being too soft and I feel I lost my baby due to this. But now I don't back down I keep at them for answers and I finally get them!
I wish you a speedy recovery and I know our babies are smiling down at us from heaven.
Thank you very much for the input. I am going to the doctor today. I couldn't take the bloating and weight gain anymore. I took a lasix 80 mg (water pill) last night and woke up with all 12 pounds lost. That tells me it's water weight and something is wrong. I wish you luck as well.
