I've been on Ovcon 35 for 6 weeks now. The first month I had extreme fatigue and lightheadedness. I felt somewhat better when I started the new pack, but now I'm in my 2nd week and I feel fatigued again and unmotivated. There hasn't been significant weight gain, but I feel bloated. I have IBS and I seem to go more regularly on this pill. I will finish the rest of this pack and then try Seasonal.
