Femara vs Soy Isoflavones

How to choose is the question? I have gone through 6 long cycles of Clomid and not one BFP. It is obviously time to move on but to where? My doctor has given me the choice of doing Femara next cycle or injectables. Unfortunately all of my Flex pay has run out so now I am truely paying out of pocket. I can't afford the injections next month plus the Ovidrel shot and the IUI. My insurance will only cover the doctors visit. What am I made of money? So, I told them I would do the Femara cycle. Little did I know, Femara is about twice the cost of Clomid. What is it with these drugs, why so expensive? After researching the last few days, I've come across a natural way to looking at this situation that's a fraction of the cost. Soy Isoflavones appear to be the "natural clomid". Appearantly  it acts in the same way clomid does in tricking your brain that it's low on estrogen. So this causes the body to release more FH and LH the hormones that stimulate follicle development. My problem is not follicle development lately but on which side the mature follicle is sitting on. Which is not a problem any of these drugs can fix obviously. That is not my only problem, just the latest problem. I can't help to wonder why it is not common practice for the doctor to take out the ovary that is related to the tube that is removed. I have read that if one ovary is removed then the other makes up for it and produces eggs every month. If this is the case, then I wish he would have just removed my left ovary with my left tube and then I wouldn't have to play these games of stimulating the wrong ovary for two cycles in a row. My patience have run dry. So, what next? Do I jump in and spend $300 + on Femara next month and keep my fingers crossed or do I attempt the cycle with the natural drugs.....and keep my fingers crossed? I would really be devestated to waste another cycle because I didn't take the prescription drugs. I've contacted my doctors office to find out why they haven't called in the prescription for the Femara yet, I read today that sometimes Femara is covered because it is generally used for breast cancer. Although, I don't have breast cancer so I'm not sure why my insurance would cover it but it's definitely worth a try. I'm keeping my fingers crossed. I'm so happy it's Friday.
