Summer, if I had to attribute to one single factor, I would have to say its acupuncture. Cos there was a period of time when my pulse is very erratic n unstable, n according to Dr Zhao, this kind very difficult to get pregnant. So with regular accu, my pulse supposedly got a lot more stable n strong. The accu really helped my lining too. On CD11, my lining was only 5.7mm. So I went for 2 sessions, n had 2 bowls of red bean soup, n on CD14, it was 8.2mm. By CD17 (day before ET), it was at 13.0mm.
