Multiple miscarriages with PCOS but have regular cycles? Please answer..? I got only one answer need more.plz?

Partner and I were trying for a baby July of 08 got pregnant in September of 09 sadly it ended in a missed miscarriage at 8 weeks found out when I was going to my 10 week appt. I thought ok we could try again because I heard miscarriages happen often with the first. So we tried again in January 09 got pregnant in February 09... I was so happy excited etc... I even tested before my period was due and got a light positive. tested again the following day in the morning got a positive again.. 3 days later I started bleeding and I knew i was having a miscarriage so i went to the er and they said the pregnancy test was negative. This was a really early miscarriage. Ok so now I been thinking I might have PCOS. I have alot of those symptoms for example... excessive hair... I find hairs on my neck and my chin at least 1 everyday.. It's disgusting! At night I could be cold but find my self sweating like if I had menopause and I'm only 22 I have gained weight since my first miscarriage so yes I'm a little over weight.. The only thing I dont understand is that my periods are regular never missed and do ovualte because I fell pregnant quick with my two pregnancies. So what do you think its going on? Any of you gone trough this? I have an appt in a month and will be taking all kinds of test I just dont want to go trough another miscarriage its so painful. Thank you.
