I wouldn't run nolva at all on cycle. Though it helps block gyno from forming it doesn't block test from aromatizing so you end up with a build up of e2. Nolva is not an AI its a serm. But in your case yes just continue but think about picking up some aromasin to bring down your e2 as its probably high and also aromasin has no rebound effect unlike letro or adex.
During cycle you can include Black Lion Research's Formeron which is an AI that will also help you increase test production and reduces conversion to estrogen. Using Formeron in your cycle will help keep you dry and depending on the dosage use even muscle growth.
What are you planning on running during cycle? Depending on what you will be using you can either do a nolva/clomid combo or just clomid during pct.
