Ok, confused please help girls i need some support!!! desperate....?

Ok, I started the IUI treatment, i got my period on 03-11-10 so i go for my 1st ultrasound on the 12th, and on the 13th i start with the injections and pills (metapur, fostimon, and femara) so i go today for my 2nd ultrasound and my endo said that the follies are not big enough!! i think there 10mmm or something like that. today is CD 7 so he told me that we are gonna stop the IUI and that i need to keep taking Metformin but increased it from 1500mg to 2000 a day! sooooo i'm so sad and frustrated!! I don't know what to do?? i know that i'm determined to loose weight and exercise since i know that would help allot! but i'm not like super obese but i am on the chunky side!! but im just so disillusioned i just wanna give up!!! so do u guys think i still have a chance on maybe getting preggo this month??? or should i just forget about it for this month?? I also forgot to mention I Have PCOS : ' (
