Everyone reacts differently to metformin, since it is a drug that helps the body be insulin sensitive there is no way you can hurt your chance for using it or it working on you.
I've been on Metformin since the start of 2004 and its not helped me with the weight loss, weight loss on met is a side effect of the drug its not what the drug is for, and only a small % of people have that side effect and most who do it doesn't last for long once the right dose is reached and things stabilize.
I always take my Metformin right before I go to sleep every night along with my Lantus injection ... I don't know much about BCs and met but I do know that Metformin can make you more fertile in general and that some BCs are not as effective as they might well be because of it (according to the manufactures info and what my gyn told me about the combo of the two - was told if I was to use BC that I had to make sure I had a back up method also in place - endro confirmed that back-up was strongly supported .. good thing I don't need BCs)
