do i still need novadex

i have been taking cyp and eq for 12 weeks. i have also been taking 10 mg novadex every day and no gyno or acne thus far. i will be startnig clomid in three weeks. I only have enough clomid to do the standard 300/100/50.
questions
1) do i take all 300 mg at same time or split it up.
2) i am running out of nova, i have 22 pills left 20 mg, can i continue taking only 10mg or should i up it to 20, and if i do up it when should i do so.
I can always order some more nova if needed.

1) yes you do take the 300mg at once
2)if your talking for pct i would up it to 20 for pct
