Guys

I took my last shot of Test C today. I now wait 18 days before I start Clomid. My question is I have been taking 10mg of Nolva throughout the cycle. Do I continue that but up the dose to 20mg from today or do I stop Nolva now altogether and start up at 20mg when I start the clomid in 18 days. Also when should I start taking clen ?
