Hoping to be pregnant?

My hubby and I are ttc#2 and I've been experiencing nausea, cramping, irritability, headaches, I have been using the bathroom more often, and backaches like crazy. We did the deed 2 days and 1 day before I ovulated then the day after. I can't test for a couple of days and the anticipation is driving me crazy. I didn't feel the symptoms so early or so strong for my first baby but I don't think I was paying as much attention to it. I am going to test as soon as I wake up when I'm supposed to get my AF but I was just wondering if anyone else experienced their symptoms sooner or stronger the second time around.
