Yes, it is definitely possible that you could be pregnant. Glycomet (metformin) and Fopymin (folic acid) help regulate your hormones and improve ovulation, which actually increases your chances of conceiving. Since you are on day 31 of your cycle, the most reliable and reassuring next step is to take a home pregnancy test, preferably using your first morning urine. Please do not worry, as this is a very common and positive step in managing your cycle. If the test is positive, or if your period is still delayed in a few days, I gently encourage you to consult your doctor to discuss your next steps.
