Dense fog symptoms and conditions

I have been on Ovcon-50 for 2 months now, and feel just horrible! I am so down and depressed. I did not take the pills during my green pills week and all week long I felt like my old self again. I took my Sunday pill and woke up Monday morning feeling like I wanted to walk into in coming traffic. The only reason I haven't complained is because I am trying to get pregnant and the doctor said that I need a strong bc to regulate my cycles so that I can ovulate properly. But this is getting to be too much! I always feel drunk or like I am walking in a dense fog at all times. And I have no choice but to take the pill right before I go to bed because the nausea is so strong!
