**lurking**
BUT< I wanted to share my experience.. a year ago when I did get pregnant, I got a "PREGNANT" urine test in the middle of the day, so excited as I was, I called my OBGYN and she had me go in that same day.. she ran 2 of their urine tests and THOSE were NEGATIVE... so I went back home, completely upset, and did another test that I had.... and THat one was negative also.. I called my OBGYN and requested to have blood drawn.. she did..
Results the next day? My betas were 185.. definately pregnant.. (unfortunately that ended in m/c) BUT regardless, False NEGATIVES are more common.
I suggest you have betas drawn. Good luck!
