I think I am becoming a compulsive freak!

Is P'ing OS a compulsion? I think it is, and I think I have it! I have a ziploc bag under my sink that holds the remains of four HPTs that ALL say BFP...and yet I STILL am taking them! I guess I am just so afraid that when I get to my first drs appt (next wednesday) that they will say um...no...BFN.. that I keep taking the tests for reassurance. Or, is it that I have no real confirmation other than the way I feel inside and the intermittant cramp to give me reassurance and these HPT's? I can not keep calling my pregnant family memebers and asking if this is ok, or if that is ok (ok I say that but I will continue to call/text/facebook you...). So my question is this: when does it become real?
