Thanks for the query.
First you have to get evaluated to find out the cause for your irregular periods
So consult gynecologist, get examined and go for ultrasound
By this possibilities like poly cystic ovaries, endometrial abnormalities can be rule out.
Then with your doctor's advice you can go for hormonal profile including estrogen, progesterone
, FSH, LH, thyroid profile, prolactin
With this workup the possible cause for your problem can be identified and treated.
Once your cycles become regularized you can plan for pregnancy.
