Clomid & Metformin

Sarah
Any success stories to share ladies? 5th cycle of Clomid (unsuccessful to date) now using Metformin too, first cycle with both (1500mg of Metformin) and period is a day late, no period symptoms either. Has Metformin messed up anyone's periods? Awaiting result of most recent D21 blood tests, tested for pregnancy today and got a BFN 😢
