Ovulation testing

Brandi
So this month I'm on clomid. I also took ovulation test. I started testing right after my period. It was low for days. Then a peak only one day. Then high for 4 days. This doesn't seem right. So I continue to test it stayed low or nothing for day. I'm 10 DPO and I got a high or positive. Why is that how can I be ovulating again.
