I'm going insane trying to work out whether every little niggle, pain or feeling is a pregnancy "symptom".

I'm only half way through my TWW (bloodtest next Thursday, so still another looong 7 days away) and most of the "symptoms" that I thought I had have dissapeared or are not as obvious.

My really sore BB's aren't that sore anymore (unless you count my constant squeezing of them to see if they hurt!!!!!!!)
I do feel really, really tired still. But then again, I always feel tired.
I have pain in my right groin area, some cramping, feel bloated and my BB's feel fuller/harder (sorry TMI) but that's about it.

I know most "symptoms" during the TWW can be explained by either the trigger shot or crinone, but has anyone had a BFP without any significant symptoms?
