No period November?

Well apparently my cycle jumped on my ban wagon of nomember november! How aggervating! Apparently its too much to ask for a period every month! This is very discouraging when ttc and getting negative results on pg test! Take anorther test and get my hopes up or keep on waiting it out.. i tested 3 days ago and got a bfn. So ready to give up on this. Its been a year of inconsistent cycles and my doctor is not concerned... like wtf?! Rant over!
