This year I have had a 48,45 and 38 day cycle, progressively getting shorter. I believe I may ofO'd but if I did it would give me a very long LP based on "usual" cycle length. Could someone please look at my chart and tell me if you think I am actually in TWW? If I did O when I think I did, I've had heartburn since 5/6dpo and tugging cramping 7/8 dpo. Help!
