irregular AF

This is more of a vent than anything else... I think AF is on her way. I feel the way I always do the day before she arrives. I was so sure we got it right!! But what disappoints me more than another month of TTC is that AF would be 6 days earlier than planned... which means I'm even more irregular than ever before. (I've always been 1-2 days off, but never this many!) I am so worried that now it is going to be even harder for us to get a BFP if I'm irregular. I know so many have been trying longer than I have (my sister included) but boy, I am disheartened. 😞   And the symptoms I've had throughout the month (cramping, mood swings, sore nipples, gassy) make me worry that something else is wrong if being pregnant wasn't the cause!
