I would stay TOTALLY far from the black cohosh. That stuff is bad mojo.
EPO when taken WITH an equal or greater amount of Omega 3 and/or animal fat probably sways blue but you can't use it with Clomid.
Again, Clomid by far and away best chances. no need for a trigger if you O on your own although some docs like to use them.
9-11 servings of fruit and veg is never a bad thing, it's what we are all supposed to be getting (I'm falling pretty short on that myself :p)
Trying to find out when you are hyperovulating and TTC only in months you are, would cost a small fortune and take a long time to conceive, additionally as we have seen, there's no guarantee even a little for twins - we've seen people who released two eggs or even 3-4 who only conceived one. So that would be a huge outlay of money for no guarantee. Plus you'd be hard pressed to get a doc to go along with that as they are generally not supportive of twinning, and additionally additionally LOL, you only are able to take Clomid for 6 months at a time and so you cannot be skipping any months on Clomid, since that would be your best chance by far anyway.
Don't worry about the odds and percentages, those don't mean that every individual has that chance. It's not a dice you're rolling with a certain number of sides, it's the average across the population. Some people prob. have less, others more - no way to know your individual chance. :) Just feel good that you have as good a chance as anyone does.
