According to glow, my period starts after 2 days and I am too scared to test. Part of me says I could be pregnant but then I feel I would not. I have PCOS and is on metformin. But I have missed pills here and there and not taking them regularly which is totally my fault. Yet again I have symptoms like sore nipples since 3 weeks and CM light and egg white. Could these be signs or just false alarms. I really want to be pregnant!! :(
