I'm going to answer the second part, since the first part of your question was answered. Yes, obviously, there's a way to check insulin levels, actually your doc should have done that! You need to see the endocrinologist, the insuline levels are tested in the lab using a simple blood sample. Just ask for that and maybe an oral glucose tolerance test as well. The insulin levels (insulin is a hormone) will tell you whether the insulin is high in the blood (which is very likely if she has PCOS, the pancreas is overactive and secrets much more insulin than needed). The glucose tolerance test will tell you whether she is already insulin resistant. If she has PCOS, these two tests are a must, since the danger of becoming diabetic is rather high. When I was first diagnosed my insulin levels were very high (3 times the normal amount) but I still responded normally to the oral glucose tolerance test (my glycemic levels were normal). This means that my body still has the capacity to manage insulin - the cells are still sensitive to it. Unfortunately, in time, this condition progresses inevitably - for one, because our pancreas can only make a certain amount of insulin during one's lifetime and because the cells become resistant when exposed to excess insulin. So definitely get those checked. There is an obvious conection between insulin resistance and PCOS - esp. since infertility is often treated with metformin, an insulin sensitizing drug. Best of luck!
Well, as far as I know, Krimson 35 is pretty much birth control. I was first put on birth control to "regulate my periods," but I was not trying to conceive then. Are you trying to conceive NOW? Did you make that clear to your doctor? You will NOT be able to conceive on birth control, obviously...
I suggest you go back to your doctor (or find another one) and make sure that you explain your worries, so he/she can explain to you guys what PCOS entails. I actually recommend going to a reproductive endocrinologist; it's their specialty to deal with cases like that. They will be able to tell you the best course of treatment to increase your chances of conception. There are no guarantees here, though... It really depends on your particular case (age, symptoms etc.)
I also have PCOS, and I was on birth control for 7 years to regulate my periods. It does not, however, cure PCOS; it just makes sure you get your periods every month. I'm not sure how much you know about it, but in most cases a woman with PCOS does not ovulate regularly or at all. And yes, your female child has about 50% chance of getting it also.
Again, I recommend you go and see a specialist!
