Your doing the right thing by using the NOLVA now.
I would have suggested using an AI during your whole cycle
to avoid problems like these but thats too late now. Stick with the PROVIRON too 50mg daily. Use the NOLVA at 40mg daily until symptoms reside.
Nolva and clomid are the same. They are both helping against gyno but the problem is that you need a lot more clomid for a similar effect. Proviron prevents gyno but once the estrogen is already present it will just prevent from raising anymore..
