Ok warning whinging post.........................

Today is CD16 and still no O. My last cycle I didn't O until CD22 but I truely believe that my body was still sorting itself out after the pregnancy. So having taken Clomid on days 4-8 why isn't it making me O now!!!!!!! Isn't that what it is supposed to do??? I just want to be normal, is that too much to ask! I really need it to happen this month. I don't think I could manage AF again.
