I'm also taking EPO, two 1300 mg softgels orally and one vaginally at night, which I pierce before I insert. Like others have said, EPO does not induce labor--it only helps soften your cervix to allow easier effacement and dilation when your baby adn body decides it's time. Like Evie'sMama said, using EPO is quite similar to having sex for the prostaglandins--although the prostagladins in semen are apparently much more concentrated an powerful. So therefore, EPO is at least as safe and non-invasive as sex at the end of pregnancy. And I'm sure we'll all agree that, at this point, inserting that little tablet is much more fun than sex at nine months pregnant, ha ha!
I've never been checked, and I can't feel my own cervix, but my MW seems to think that EPO is beneficial, so I'm just keeping a positive attitude and trusting that (since i'm 40 weeks tomorrow!) my body is gearing up for the birth day! Hopefully the EPO will simply make the birth day go a bit smoother. And--on the off-chance that I make 42 weeks and have to be induced--EPO supposedly makes inductions go easier, as well, as it has been ripening your cervix.
