Okay, short background. 42 years old, been trying for 4.5 years to get pregnant with our 2nd. First nursling weaned at 3 years (2.5 years ago) so obviously that isn't an issue anymore. I decided to try TCM (Traditional Chinese Medicine) as a last ditch effort to improve my chances at my age especially now that DS is in kindergarten and I have time to do it. I had my first month of acupuncture in mid-September and Chinese herbs starting on the Sept. 30th cycle.
I was devastated a couple of days ago when, right after I had awesome EWCM and BD'ed with hubby, that I had a light period. My BBT temps dropped on Sunday and I started to spot that night, then got clots/brighter blood but still pretty light flow that lasted until late Monday/earlyTuesday morning (I'm usually at least three days, regardless of how early it comes). Temps were lower on Monday and Tuesday and I went in for another acupuncture session on Tuesday. Today, my BBT is as high as it usually is after ovulation. http://www.fertilityfriend.com/home/11f6c3 
Do you think the crazy temps are just perimenopausal issues and this is a new cycle or is it possible I really did O and had a late temp rise? My acupuncturist was truly surprised I had such a short cycle (but I've had some crazy cycles this year). I'm crampy today and feel nothing like I usually do at the start of my cycle.
I suppose I just need to wait and see but it really was hard for me yesterday. We'd really like a second child and I felt like the whole menopause thing was shutting the door on me.
