Cycle day 41!?!?

What is going on with me?! My cycles are usually 30 days at most! I had some spots of blood when I wiped once last Tuesday when my period was suppose to start.. nothing since then.. not even feeling like AF is on the way! But I don't necessarily "feel" pregnant either. Last test was negative taken with FMU on Sunday. Husband won't let me buy anymore tests until this weekend! Anyone else turn out to be pregnant after a negative test taken after AF should have showed? Or pregnant but no early symptoms??
