5 dpo and searching for phantom symptoms

I know, it's way too early to feel any symptoms...and truthfully, I dont know if I really feel any. With that said, I think I may have felt very very slight nausea in the AM and PM yesterday, but you could also chalk that up to a late night at a wedding the night before. I remember that my first pregnancy, I didn't feel any symptoms and only realized I was pregnant b/c I was late for AF by 6 days. I did feel cramping around the time that AF was due, but I chalked it up to AF. In my 2nd pregnancy I felt nipple sensitivity and had unusual amounts of CM starting at 6 dpo. I'm not sure what to expect this time around, and I guess I'll only know when it gets nearer to AF time and I either see her or I dont. I'm planning to test on 3/23 - 3/25; AF is due 3/24. Typically, I like to wait until AF is overdue, just so that I'm sure to see a clear sign on the HPT....but who knows...if I see a jump in my temps to a triphasic pattern, I may cave and test a day or so early...like I did in August for my last BFP. Thinking positive and continuing to repeat my mantra - I believe I receive!
