Hi Sarah and Welcome!
Firstly I don't know the answer to your Q but I'm sure someone will pitch in soon. I did want to let you know that you should never take Aldactone (aka Spironolactone) when you are TTC (trying to conceive) as it can cause genital abnormalities in baby boys. I know you said you have stopped it as you don't suffer with excess hair but I thought I should point this out just in case. Btw Glucophage (aka Metformin) is safe to take when you are ttc and some people have also taken it successfully during their first trimester too.
Good luck with ttc and I hope someone can answer your Q soon
