Hi we have been ttc for around 4 years we have one dd who is 4 1/2. since she was born I have had 4 periods (one of which because on norethisteron) no natural period in over 2 years . Also have excessive hair and have gained alot of weigh , skin tags and some acne on my arms. I suspected pcos as does my docter but ultrasound scan yesterday said everything was fine no cysts and no obvious problems , doctor will get results by next week so I will make appointment to discuss but in the meantime does this mean its not pcos ?? is it possible or even likely to have pcos but no cysts ?? and if not any ideas what it could be ??. So frustrating just want answers now and hopefully some help.
