Missed period, negitive hpt.... :(?

Alright, so now ive missed my period for 2 days now, I havnt changed my diet, or gained or lost any weight, I havnt been stressed any more then normal this past month and my periods are on time usually every month. This is the first time the hubby and I are ttc... I took a hpt today, but it was negitive :( I used one of those early responce ones too... Has anyone else used those and ended up with a false negitive? Im going to wait a few days and try it again, that is if my af doesnt come first... But I have been feeling off lately, tierd and whatnot, I usually get cramps the day before my period but I had some off and on for 3 or 4 days, non yet today tho, if I were preggo would I feel cramps like that? and I did have a little pinkish, clear discharge when I wipped that lasted for 2 days as well about 4 days ago, has anyone else experienced that? Im hoping for the best and have my fingers crossed, I just want to kno if anyone else is or has gone through how im feeling and ended up being pregnant.... Thanks in advance, and sorry if theres tmi...
