Can I obsess a little?

Here are my symptoms:

Sore bbs
Runny nose
Spotting
Pain on the left side of my uterus yesterday afternoon prior to spotting
Uterus feeling full and a little crampy
and here's a nice one, a sore, itchy vagina

These symptoms are all within the realm of possiblity for early pg.

I looked at the cycle gallery on Ovusoft and some FAQs about HPTs and implantation and you need to wait 2 days from the time of implantation spotting to test. Soonest might be tomorrow. But what if it is just due to my being sick last weekend? And what if I am pg and it fails again?
