Dis couraged

I'm really so over this ttc baby#2 and having pcos really sucks. Went to a specialist in august I was given different meds to help with the pre diabetic issue of it cause metformin was to harsh for me. I am taking acaarbose and so far it's really well. I Don't know if I've lost weight yet though. I haven't had a period since July 2nd. I have only spotted briefly for two days in august and September. My bestfriend and now my sister (who has just had a baby in April) have both broke the news they are pregnant this week. My stomach has been cramping for three days now and my breast hurt midly and I'm eating like a cow. I'm just praying I am pregnant already and it's just like with baby #1. I didn't know until I was 13 weeks. My husband is going to be devasted when he hears they are both pregnant and I am not after more than a year of trying. Smh why me? Why us? We love kids. Our daughter is our world and she so badly wants a sibling. If it doesn't work out this month I am seriously considering trying a round of clomid. This natural way isn't working it's depressing me and I'm at my lowest now.
