I definately recommend it - I used to drink it to help regulate my cycles so I knew it was effective for me.

I drank RL tea from 35 weeks, and had effective BH's straight away up until delivery at 40 weeks exactly. I wasn't drinking it for labour, but moreso to prepare my uterus for the afterbirth recovery. Worked a treat! I'm still drinking it (6 weeks postpartum) and will continue as per usual to get AF back into a regular pattern
