Hi, I m 34 years old and my husband is 31. I have 2 daughters (age 13 and 4) from a previous relationship (my husband has no children...yet!) and we re now trying for baby number three. I have always had extremely irregular periods and found out about 6 years ago that i suffer from PCOS after trying for over 2 years to become pregnant with my 2nd child. I was eventually able to conceive her after being put on Metformin. My hubby and i have been TTC for over 8 months now, without any success. The doctor recently (1st Feb 2016) put me back on Metformin 500mg daily, as that worked for me last time, however this time around I ve been getting some strange side-effects. I m always extremely nauseous sometimes to the point of vomiting, constantly emotional and crying, depressed,and now I ve started getting a whiteish, clear, greenish coloured discharge from both nipples. I did a test, but it was negative. What should I do? We re desperate to have a baby. Please help...Many thanks
