Hi I'm 40 and me and OH been trying for 2 years with no luck. I have recently been put on metformin as have a variation of pcos. I've only started it this cycle and have been lucky with very little side effects. I did notice a big increase in ewcm this month and for the last week (im cd27/10dpo) I have had the most weird vivid dreams, really bad wind!, nausea on and off, and now tender breasts which is not common for me. Oh also very tired in the day and fallen asleep at work nearly every day last week! Oh yes and cold!! So my question is as it affects hormones do you think these symptoms are brought on by the metformin or could I just be in with a chance this month???
