I believe in EPO being beneficial, wholeheartedly!
In my normal cycles, I have difficult cramps and heavy bleeding...until I began EPO. After a couple of months, things really eased up. I'm a big supporter.
As far as in pregnancy, that's great, too! It encourages the release of prostalgandins, which aid in softening, and dilation, and even position of the cervix. With the exception of my 1st, which was a pre-eclamptic PROM/delivery at 34 weeks, I've NEVER ripened before being induced or sectioned before dates. However, with my last baby, a VBA2C, I began taking oral EPO at 32 weeks when I switched from fish oil, and began also adding in vaginal EPO at 35 weeks. I went past my due dates, and then my OB ruptured my membranes to get labor to start (hospital was worrying since I was past dates) and my labor was only a few hours. The difference was I was WAY soft and squishy, and dilated enough to break my water-something that hadn't happened before.
So, I'm doing oral EPO right now at 33 weeks, and will add in vaginal EPO in 2 or 3 weeks.
