Mood Swings on the Pill

I used to take the pill for years up until about 5 years ago and was fine. Just started taking it again about three months ago and have been having massive mood swings. It's like I have constant PMS! I've changed to a different contraceptive pill three times and still feeling bad. Wondering if anyone else has had similar problems? I'm about 6 days into trying one called Trifeme. Also does anyone know how long it should take before you will start seeing changes if any?
