PCOS Women! is it true that it's really easy to lose a baby when you have PCOS? My friend also has it and she said she has had quite a few really early miscarriages. I'm worried because my jobs messes up my sleep patten, diet, eating patten and is quite physical and can be stressful. I don't worry too much but I am constantly doing pregnancy tests in case I am so I don't do something to jepodise it. Need to know if I'm overreacting lol x
