Oiling your bits-any time from 34 weeks-u can use olive oil, EPO oil etc...
In regards to EPO and RTL I have followed this regime previously posted here from another PF trimester lady. I took a capsule of RTL instead of a cup of RTL so have probably had more than this list suggested.
32 wks - 1 cup RLT
33 wks - 2 cups RLT
34 wks - 3 cups RLT, 1 EPO orally
35 wks - 4 cups RLT, 2 EPO orally
36 wks - 5 cups RLT, 1 EPO orally, 1 vaginally
37 wks - 5 cups RLT, 1 EPO orally, 2 vaginally
38 wks + - 5 cups RLT, 2 EPO orally, 2 vaginally
Good luck! Hope it works
