More questions to follow a short whine... I'm sitting at the computer wrapped in a blanket being cranky because the

showed tonight & did so with a VENGEANCE! Stupid Cramps.
AF showed up around 9pm. Do I count today as CD1 or tomorrow? If I count today as CD1, this month is 2 days shorter than my last two cycles. They were both 29 days. This time I O'ed on CD 14 (instead of 15) and my LP is 13 days (instead of 14). I'm just concerned that my cycles are going back to how they were pre-baby. My cycles were super-short (20-23 days) with AF for 7-10 of those days. I wasn't charting then, so I'm not sure if my LP was really short or if my follicular phase was short. Either way, it took us 2 years to get a pregnancy that stuck. I had 1 molar preg, an early m/c (7wks), an ectopic (ruptured at 7wks & lost a tube) & then a chemical pregnancy. I was thinking about trying B6, but then also thinking my LP is still good at 13 days & maybe I should wait another cycle or 2 before I go trying stuff. Advice? Any BTDT moms on cycles pre & post Baby?
Sorry for the long post, just sitting up alone & thinking of stuff to worry about.
