OMGOSH....yes...defn. I think the mind plays a huge role in conceiving and labour itself......

Whilst all my children appeared on or there abouts on their due date, i honestly believe i was ready mentally for labour at that time.

My last labour (2 weeks ago....) i wasnt physically exhausted from my labour (only 3 hrs) but i was mentally exhausted. It took sooo much outta me preparing for the 2nd stage of labour, the transistion, and the pushing i honestly have never felt so mentally exhausted like that before....
The mind is soooo powerful. Ive said this before, but will say it again. Midwives told me in my last contraction NOT to push.....(his head was out.....) she said if you push, you will tear.. It took so much energy, focussing, and willpower NOT to push. My mind was in overdrive. It wasnt my body that prevented me from tearing....it was my mind.

YOur on the right track it seems.....GL.
