I have 2 apps downloaded on my phone. One app said I should start my period yesterday. Glow says not til like Thursday. I'm not really for sure because this is my first month off the mini pill and my periods were slowly getting longer and longer. I start aching (not really cramping) yesterday with intense back ache. Woke up this am and still no period. Lots of watery CM. I guess to make a long story short, how many of you guys had cramping before AF and still got a BFP?
