Early signs of pregnancy or am I just crazy?

Alexandria
I'm 10 po and I'm supposed to start my period next Tuesday, this was my first round of using clomid and I'm really hoping it worked. But I've been feeling sick after I eat these last few days and I've been having crazy cramps that don't feel like my normal period cramps. I'm waiting to test till later this week but I'm just wondering what you ladies have gone through or have seen as early signs
