Ovcon and irritability

I have been on Ovcon 35 for 4 months. Put on it for continuous use to prevent endometriosis. I had minor symptoms before the pill. I experienced spotting and breakthrough bleeding most of the months for at least 2 weeks per month. I could live with that if I really had to , althought very annoying. I have had slowly progressing depression (including insomnia, irritability and memory loss)until finally I had a manic depressive episode where I had suicidal thoughts. It took 2 days for the "fog" to clear and to realize that it was the damn pill. I stopped it immediately, obviously this is not a side effect I care to deal with. Feeling better already!!

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.
