NOOB thinks --> Parenthood=Weight Gain

My name is Eva and this is my first message. I will start off with the fact that even though I worked out M-F during my pregnancy ( I was in the Army it was mandatory) I still gained almost 50 lbs even though all I craved was healthy foods. I was still 40 lbs overweight after my precious little lady was born. I continued to eat healthy and work out 2x a day for an hour each time.... weight still piled on. It is unfair. I was 135lbs before I got pregnant and I was SO happy. I even got my belly button peirced because I was finally confident in my body. I have had the thyroid checked out and the bottom line is there is no reason that I should be gaining weight at an obnoxious rate . I am almost 200 lbs and I am only 23. I just dont understand. I have been trying so hard to just get under 180 and it is just so hard. I know that this is not the best way to go about it , but I am only eating around 1000 calories a day. My goal is 1200 so it isnt too bad . I hear what everyone is saying , I have a knowlegde of human anatomy and the starvation mode that your body goes through, and I also have tried just woring out , working out with a low(ish) calorie diet ,and with a higher I have also tried just relaxing and letting my body fix itself , but none of that work ( it has been almost 2 years and I still have my baby pooch , weight and hormone irregulation) Bottom line is I feel SOOO much better and I dont know why, eveything I read and hear points to the fact that I should feel miserable and tired. I have only lost 1 lb in 2 weeks and that one lb feels like 20. I have more energy and I am happier all the time ... I am just confused. If anyone can help on this subject , WITHOUT being rude I would appreciate it.
