I am 43 years old, have had a tubal ligation but am taking Ovcon-50 for the first time because of endometriosis and frequent, very heavy, periods. I am now three weeks into the first month, and have been experiencing fatigue, interrupted sleep/vivid dreams, nausea, irritability, dizziness and dehydration (I've had to have IV fluids at an Urgent Care facility twice in the past week). Is any of this normal with the use of this drug? I don't want to stop it yet because I want to see how it affects my menstrual cycle, which has been a nightmare. However, these symptoms are serious and I am wondering if it is due to the drug. My PCP has gone on vacation, so I am kind of stuck right now.
