TTC and counting cycle days, I lost track somewhere and I'm on cd18 but I thought I was on cd16 so this is good!!!!!! I am experiencing a lot of back pain (I always have it but it's a lot more now) I'm nauseous after I eat anything and I'm so cranky. I don't know if I'm about to start or if the Clomid is making me feel this way or if I could possibly be pregnant :)
