Clomid cramps.

I’m on day 4 of clomid at 50mgs. And my left ovary (I think) has been so sore and that whole area is pretty tender. It’s not anything awful or scary. But I don’t know if I should be excited because that means it working or nervous because that means it’s not working? I just don’t know. I do not ovulate on my own. This is my first cycle on clomid. I just want it to be my turn so bad. Trying for 5 years with no success not even a scare. Any ladies going through this with me or experienced ovary pains while taking clomid?? When should I start using the ovulation tests after I finish the clomid?
