This has never happened to me before and my husband and I have been TTC for 13 months now. I was getting some mild cramping From Friday night into Saturday morning...even told hubby that I think my period is coming.  So Saturday morning I have this little smaller BB sized dot on my TP after peeing and the smallest amount of pink staining on the TP around it.  Nothing more came after that.  Cramping has subsided.   I've been praying for a baby all month because my birthday is on 5/26 and promised myself I would test until then.....AF is due in around 3 days from today.  My cycle is 29-34 days.  Today is cycle day 32
