ttc frustration...

I'm really trying to stay positive and not stress about things. but I'm only 24... I'm supposed to be in my prime time for having kids. yet here I am 3 years ttc and no luck. found out in August I have pcos. just finished my first 10 day provera to induce period

. finished the last pill 4 days ago waiting for af to show up. gonna do 50mg clomid days 3-7. I'm trying to stay stress free and be positive but the way things have went with me I can't help but be really negative about the clomid I just can't get it in my mind that it's gonna work.. my sis in law just had her 4th child in 6 years.. it's getting really hard for me to even see babies because all I wanna do is cry.. i just had to get all that out..
