Should I test????

I don't know when k ovulated but I know I ovulated before the 22nd because I went to the Dr due to pain and she said it shows the meds worked!!! Now I'm supper ready to test!!!! This would put me 8 days before my next cycle ...I'm hoping too see a faint line that will give me so much hope!!! Do you think I'm setting myself up for failure or its worth a try??????
