I personally didn’t go through this but I know a lady who did. She was overweight and didn’t know until she was into labour, and she was soooo shocked, as were we. She had gotten all 9 of her periods and she had a healthy babygrl. Sometimes, nature works miracles but the only thing that kept me going the first few weeks is to know that there is no more tampons for a good while and I was happy at the thought, but maybe you are feeling everything sooner and you just had a couple of periods and I think that you would owe to having 2 children, so you can feel the movements alot sooner than a firsttimer. Good luck and see a doctor
