Is Clomid Taken With Provera In Case Of PCOS?

hi

i have pcos. i have had 4 rounds of 50mg clomid and metformin 1500mg, only 2 rounds ovulated, menstration occured on day 32. i am now on my 5th round clomid 100mg and metformin 1500mg. my blood progesterone level on day 23 was 32. what day would i have ovulated?. im now on day 35. would an increase in clomid dose effect the length of my cycle? hpt is neg. I normally take provera to induce menses on the cycles where my blood progesterone was low and i knew i had not ovulated. how long should i wait?
