I couldn't imagine not finding out until 16 weeks!
yes. symptom wise, looking back i had gained weight. however, at the time i was dealing with food issues and honestly thought it was that). i did experience some nausea, HOWEVER, it was flu season. yes, i missed a period BUT my periods were irregular and it was normal for me to use my BC as directed and still miss a period. i didn't start to show until 18 weeks, and even then it could be mistaken for bloat. by 20 weeks it was obvious, however. and i felt him move for the first time at 20 weeks as well.
since having my son i am SO in tune with my body, and lucky for me my cycle is very normal
but dang. i couldn't believe my doctor when he said i was 16 weeks. my mouth=open wide and jaw was on.the.floor.
