Diagnosed pcos and clomid?

I was diagnosed sometime in december with pcos and i had what i believe is called a endometrioma cyst that was removed with laproscopy surgury and i had a hysterscope done also to make sure my tubes were open...well in january the dr. Said i ovulated without any meds. This month i used 100 mg clomid and 2 days of 50 mg clomid. Weve been bd. Every other day since i started taking clomid the 30th of january i had a pos. Opk 3 days agoand the control line is getting fainter every day. Does that meen i ovulated 3 days ago? Do you think i have a good possibility of being pregnant? Since weve been bd every other day
