My period is usually every 28 days, lasts for 4 days and is very predictable. I'm usually very lucky! However, in early January I missed my period completely then in late Jan/early February I've had a 2 week period. That stopped for a week and now I have another period except this time it is extremely heavy and I'm leaking within a few hours. Is this normal? Should I be speaking to my doctor? What can I do, if anything?

I'm not taking any contraception and I've been taking aripiprazole for about 4 months for mental health reasons.
