Thanks for the query.
Sometimes in perimeopausal age group irregularity in periods can be seen due to hormonal
Though the symptoms you mentioned could be more possibly due to hormonal effect.
Anyhow better to consult gynecologist once, to get examined and go for ultrasound
once to detect the possible cause for your problem. Ultrasound can rule out any possibility of ovarian cyst
After that with your doctor's advice you can go for tablets to induce withdrawal bleeding.
