When I got pregnant with my daughter, I knew I was pregnant the morning after conception(I know this seems weird). I didn't have any symptoms or anything except that I felt different and just knew I was pregnant. With my next pregnancy, I didn't know I was pregnant until I was 3 months along!!! Although I should have known a little earlier (hindsight) because I was moodier and more emotional. With my son, I found out by taking a pregnancey test. We had been trying to have another baby, so everytime I was a little late I took a test, but I didn't have any early symptoms with him. So to sum it up. Each pregnancy was different for me in the early stages.
