So disappointed

Laura

AF was due 10/1 still hasn't shown up. My boobs hurt and I've been cramping. But the bullet this morning and tested. Got a BFN and still no signs of AF. I don't get it?! I came off the pill at the end of July and got a normal period in August right on time. Any ideas and or advice ladies?! I guess I should add I just turned 30 in July. I'm 5'2" and 230lbs. Been trying to get the weight under control but I suck at it.
