I have made it to the wonderful 12 week mark :-D I am preg. with fraternal twins, due in July. I do not feel or look pregnant though, besides my sore bbs...I was told that since this is my 2nd pregnany I would show earlier, esp with twins -- NOTHING yet. I guess I should enjoy it because sooner than later I will prob. get a pretty big belly with twins. I didn't show big time until about 7 months with my DS and he was a 10lb baby. Just happy to be at the 12 week mark.
