I have not had surgery yet, but have a lot of experience with PCOS. I was diagnosed after a year of trying to conceive with clomid through my OB. I went to a specialist (a reproductive endocrinologist), he took one look at my labs, did a ultrasound (which clearly showed the "string of pearls" configuration of follices in my ovaries, and said, "Okay, here's what we're going  to do." I started metformin, clomid, and HCG trigger shots, did insemination, and got preganant with my son after the 2nd cycle. Three years later we decided to try again, got pregnant twice with two miscarriages (most likely NOT related to the PCOS, my MD said, just bad luck!), but then tried again and got pregnant with my now 17 month old fraternal twin girls. So I had a really good outcome with everything. I'm not sure if my PCOS was totally because of my weight because my periods were always troublesome, even as a young girl when I started (and not overweight). But the one weird thing with me was that my periods were ALWAYS regular!! I had them every month, 28 days apart, and those stupid ovulation kits ALWAYS told me I ovluated!! The best thing I did was go and see a specialist. The metformin made a huge difference in my labs. But your insulin resistance being normal, and your periods now being normal is a awesome leap!!! I wouldn't hesitate to talk to your OB or even see a specialist if your insurance allows you to. I can honestly say, that there has been no greater stress in my life than that of infertility. It makes you sad, bitter, mad, hopeless, and makes you feel like your body is failing you. After everything you have gone through to make a healthier "you", you deserve to have this happiness. I hope everything goes well for you, and look towards professionals who seem to want to DO something, rather than sit around and "wait". That attitude drives me nuts!! Good luck!!

You don't mention how much pop you were drinking, but, if it was a lot, then I'd wager that played a big part in your weight loss.  At least, it did in mine.  I have a similar story where, in a couple of months of not doing anything else other than restricting my formerly heavy consumption of coca-cola, I lost 11 pounds.

The last time I took metformin was the day before surgery.

Don't lose hope.  Let me tell you about my story with PCOS/fertility.  I kept having painful cysts on my ovaries back in 1999.  Finally in 2000 my gyno decides to do exploratory surgery and during the course of the surgery he drained the cysts, found my fallopian tube was attached some place it wasn't supposed to be and corrected it.  After surgery he told me I had PCOS but never explained it and never mentioned it again even when my weight started shooting up.  Eventually he told me I would not have children unless I was prepared to have heavy duty fertility treatments.  I did.  I also did in vitro.  Nothing worked.  Life went on...years passed and I finally found a Dr. that would treat my condition.  He put me on Metformin and I took it for over a year.  I met my current husband, explained that I would not be having children without the fertility treatments.  3 months later I was pregnant.  My Dr. explained to me that it was the Metformin that was responsible for my pregnancy.  My OB made me go off the Metformin and my pregnancy progressed normally...I had a boy that was 6 weeks early but in good health.  6 months after the birth of my first child I got pregnant again and miscarried at almost 12 weeks.  I waited 6 months and tried again.  I had more problems with my second pregnancy than with the first.  Too much amniotic fluid, too much weight gain...etc.  My water broke early and it was another c-section for me and luckily my son was okay.  After that pregnancy my hormones were insane and still are.  I tried going on Metformin again but didn't have luck tolerating it this time around and it didn't feel like it was working.  Since having my second son I have gained another 40 lbs.  I was in such shock when I found out that I was even pregnant to begin with for my first pregnancy that I must have taken 6 pregnancy tests and still didn't believe the OB until I heard a heartbeat.  I did not get pregnant until I had become resigned to the fact that I was not going to become a Mom.  I don't know if that had anything to do with it--less pressure or what.  I will tell you that the year before becoming pregnant the first time I got back on the pill and did the Metformin at the same time.  The pill masks the PCOS...not sure if you were aware of that or not.  Don't give up!!!
