I have PCOS and I take MetFormin as most do. My husband and I are trying to conceive now that I’ve started my medicine. My period isn’t supposed to start for at least 4 days but I keep having pregnancy symptoms such as: gas, constipation, nausea, fatigue, and the other day one of my coworkers were eating spaghetti(which I love) and the smell made me so nauseous I had to leave the room until he finished.. I took a test yesterday and it was negative. Am I just crazy? Or should I take another test? If so, how long should I wait. Any advice would be great.
