My doc has talked about Metformin and I have adamantly refused. It seems like everybody who takes Metformin ends up with some serious digestive discomfort during the first month (affectionally known as "metformin moments".) These effects can be somewhat lessened by taking the extended release version, but as I already have IBS I decided not to add fuel to the fire.
The other big issue with Metformin is that if you have a scan with dye, you can experience a fatal reaction. If you are on Metformin it is imperative that you get a Medical Alert bracelet stating so in case you are ever incapacitated.
That being said, Metformin is one of hte few drugs for diabetes that does not cause you to go low. It is also the only one approved for prediabetes and despite the side effects many find success with it.
What exactly were your numbers? If your doctor says you have markers for "prediabetes" that means you have it. Hate to break it to you. It pisses me off that doctors don't give pre-Ds or Type 2s more info. The first thing you need to do is get a meter and know what your numbers are. Test after you wake up (but before eating) and 2 hours after meals. Anything higher than 100 fasthing or 140 after meals is prediabetes. Anything higher than 125 fasting or 200 after meals is diabetes and that means you are damaging your body. Actually, anything over 140 causes damage (although not as much.)
Testing is critical because it allows you to make necessary changes. Have your doc call in a prescription. (you can buy without, but strips are very expensive). Choose the meter you want. Companies will send you one for free with 10 strips just so you will use their meter and buy their strips. Find out which brand has the lowest deductible on your insurance. A great brand is Freestyle. The Freestyle Lite uses very little blood and they have a great program called Freestyle Promise Program. They will send you a free meter and strips. They will also give you a card that helps to pay for the strips. You pay the first $15, they pay up to $50 and you pay the rest. So with an insurance copay and the card you would only be paying $15. Copays can be as high as $60 for 100 strips so it really si a great deal.
You also need to start cutting back on carbs. I completely gave up soda when I was diagnosed. I now drink water or iced tea. Bread should be an occasionally thing. Ideally, you should see a Certified Diabetes Educator, but if you cannot eat no more than 45 grams of carbs per meal. Many do not even eat that many. What you do eat, try to eat more complex carbs. Sub sweet potatoes for potatoes. If you like pasta, use Dreamfields. It has only 5 grams of digestible carbs so it will not cause blood sugar spikes. Limit your bread, but if you must, use whole grain (that is true of any grain). Fruit is good, but again, test to make sure it won't cause you to spike.
You need to also get a second opinion. If your doctor was concerned enough to put you on Met, then obviously you are at the very least Prediabetic. By not giving you any information on diet or exercise she is contributing to the complications you may experience. Diabetes does damage over time. Leading to kidney failure, blindness, and amputations from poor circulation. It also makes you much more likely to have a heart attack. If you get it under control now, you can avoid all that.
I'm not trying to scare you, but doctors are not telling people how serious this really is and that is irresponsible and dangerous.
A great site with all the info you could ever need is diabetes forums. Go to:

ETA: I see you are TTC. High blood sugar actually makes it very hard to conceive and makes it more likely to miscarry. If you are serious about TTC, testing is an absolute must so you know how you are doing.
