Flu symptoms,migraine,knee pain while cleansing

First of all, let me say that this website is wonderful. I have learned so much from everyone that has been kind enough to share their experiences with cleansing. This is my first time doing any sort of cleanse. So, I decided to start with the Bowel Cleanse and then a parasite one. I started Oxypowder last week and just started Primal Defense 3 days ago. I think I'm experiencing detox. I woke up with a bad migraine yesterday (which I still have), my knees are aching (hurts to go up the stairs), and I feel like I have a bad cold. How long will this last? I didn't take any Oxypowder last night and I still feel awful today. Should I wait until I feel better to continue cleansing or just wait it out? I used to get migraines fairly often, but haven't had one in awhile.
