With my first, I had extreme fatigue starting about a week after conception. And a little food aversion. But I didn't connect the dots until after I missed my period. I did know before I took a test, though, because I was charting and knew for sure when I ovulated and when my period should have started, and I waited until I was about 4 days later.
With my second, starting about a week after conception again, I had the same extreme fatigue, but paired with insomnia, sore boobs, nausea, period-like cramping...pretty much anything anyone's ever experienced, lol. I was pretty sure then, but I waited until my period was due to test.
