I am a HUGE advocate of this...
when TTC my 1st son it took me a year. my cycles were all over the place - 14 weeks, 8 weeks, 10 weeks - the shortest cycle was 6 weeks. I didnt use any TCM at this stage but was going to do so if I didnt fall preg soon. I did use acu at the end of my preg for labour prep and I had a fabulous 4 hour labour and a speedy recovery.
When TTC my 2nd son I did turn to TCM and acupuncture. I had not had
AF back since I had my son (had just stopped bfeeding about a month before). I had a session and got my period 1 week later. I then had a 30 day cycle and then got preg the next cycle. I found the acupuncture and herbs helped me immensly with this. I also continued seeing my practitioner for the 1st tri for support and to help with nausea and fatigue - this was great. I then went back to her around week 34 for weekly visits (labour prep again and also to help with back pain - fantastic). I gave birth 9 days ago at 39 wks (Same as my 1st son).
I think it is def worth giving it a go - I also found her advice on supplements etc thru the preg was fantastic.
