The last 5 weeks of my cycle a few months ago, I ended up having a high fever, the flu, and bronchitis, and I still worked out like crazy for 5 weeks straight. High-intensity cardio included. Sure, I puked about 4 times while lifting, but the high fever helped with the fat burning.

It was hard as hell, but you can't lay around when on gear. Since you are not on it yet, I would suggest resting for a bit.
