From what I hear, EPO works somewhat like a prostaglandin, which is what they would give you to ripen your cervix in an induction. (also present in semen, BTW) It is good for making your cervix soft and ready to dilate and efface. I asked my midwife about taking it, and she said they used to recommend it in their practice, until a study came out that associated it with early rupture of membranes. So they don't recommend it here anymore. But from what I hear/read on BB, lots of women are taking it without issues, so if you're fine with that, then go for it!
My midwife gave me a herbal combination to take three times a day that has pulsatilla, arnica montana, caulophyllum tha, actea raccem., and gelsemium semp. in it. (don't ask me what all those things do - she told me, but I forget!) Anyways, the idea is that it will give you a little nudge into labour if you are close anyways.
All the best!
