I suspected I was pregnant when I spotted. I never spot and my periods are always regular. But I didn't do anything right away. The week after I got all the typical symptoms - sore boobs, nausea/vomiting, food aversions (even just the smell of coffee, beer, etc, made me feel sick when I normally love those smells) fatigue, dizziness. Then the missed period another week or so after. That was all about mid-November. November 22/13 I took my first pregnancy test and it was positive. I took a second one 2 days later (the one that tells you how far along you are) and it said 2-3 weeks.
