Welcome to Healthcaremagic.
The irregular periods
are symptoms most commonly seen in condition like PCOD (Polycystic ovarian disease
I suggest you to rule out the same by getting a ultrasound
scan.If the problem is confirmly diagnosed then you can be put on specific medication from where on you can have healthy periods.
is a good medication worth of trying but it is PCOD in you then sustain too may not be helpful.
Wish you good health.
