Hi MsT123
Welcome to Moomie!
Just like SwartKat, I'm in no way a medical expert, however I would like to think that I've learnt a thing or two over the past 2 years of TTC.
I too have PCOS. Always expected it (since I rarely get my period) but was officially diagnosed late 2013. Unlike SwartKat, I haven't been so fortunate to walk the short road to getting pregnant. After 18 months of Fertomid, we started doing IUI end of March this year. Long story short, after 2 IUIs and also 1 that was cancelled due to over stimulation, we're still not any closer to becoming preggies.
Some people with PCOS are almost not impacted by it at all, while others walk a long road. You'll only know once you try. Perhaps this is the reason why your doctor wants you start sooner rather than later.
That said, I also believe that giving a 27 year old such a deadline doesn't sound right. If you were in your early 30's already it would have been a different story. But you're not. In my mind you still have plenty of time.
Also, what bothers me is that she wants to prescribe Metformin despite your normal blood glucose levels. Doesn't make sense. I could ramble on, but the short version is that I believe you should get a 2nd opinion of someone knowledgable in this field. From my personal experience I can honestly say that my Fertility Specialist is so much more knowledgable compared to my normal gynae. So I'd really recommend finding a good fertility specialist for a 2nd opinion.
A fertility specialist may want to more tests to see whats going on. I had a laparoscopy done earlier this year to check that my tubes were open etc. and it was only then that my FS diagnosed me with endometriosis (fortunately not very bad and he removed it at the time). So perhaps an FS can shed more light on your initial problem (the clots and so on). Also, as SwartKat said, there are options such as IUI and IVF for people with fertility issues and an FS would be the best person to advise you on that and tell you when it would be time to start looking at those options and which ones are more suited for your case.
With regards to diet, I've learned not to trust most medical professionals on this topic, since they have been indoctrined into thinking a certain way. What's important to me is eating proper home cooked food. Avoid processed and oily/greasy food. However a bit of proper animal fat can only do you good in my opinion. There are many similar diets out there that aim to get you healthy by controlling the ups and downs of your blood sugar and I still believe that is the key to success. How they attempt to do it differs, so you're going to have to make up your on mind on that one. These are my 3 favourites although I do not strictly adhere to any of these in particular:
1) Low carb high fat (Banting / "Tim Noakes" diet)
2) Paleo diet (similar to Banting but there are differences)
3) Low GL diet (some books by Patrick Holford comes to mind)
Excercise can only be good for you, although I have to admit that I haven't done that in years.
With regards to your skin (and hormones), I'm not familiar with Diane, but I can say that my own skin was beautiful once my normal gynae prescribed Yaz to me. I would consider using it again.
Lastly, on motherhood. Despite the PCOS I miraculously fell pregenant with my son when I was 30 (married for little over 2 years at the time) without us even trying for a baby (I wasn't even getting my periods at the time, so what are the odds of conceiving). In some ways I never felt ready for it and would always think that there were more things should have been planned and in place before we could have a child (I'm also a planner). But when I saw that positive pregnancy test, I knew that we were just going to have to wing it. And we did. It wasn't always easy and my son wasn't the easiest baby, but at least once you are pregnant, you have another 8 months to prepare yourself for your new life. So what I'm trying to say is that if you do decide to go ahead now, let go of the fear that often comes with this type of decision you have to make and just go for it. Decide that you are going to make it work.
And if you decide to wait some more, put it out of your mind for a while and don't keep on worrying about it.
I hope that in my ramblings you at least could find something of use to you.
Hope to see you around soon.
