Ovulation testing!! HELP!!!!

Toni
I took a ovulation test Monday, no smiley.
Tuesday I took another one and got a smiley face, hubby and I had sex. Wednesday took another ovulation test and got another smiley face but hubby wasn't in the mood. So no sex Wednesday night. Thursday took another test and didn't get a smiley face but hubby and I had sex. 
My question is should I take another ovulation test or was my ovulation days Tuesday and Wednesday? 
Any help would be helpful!! We are new to TTC. 
Also I do have PCOS and currently on 2000mg metformin. And this is our 3rd round of 50mg clomid.
