Thanks for the query.
Chronic chlamydial infection can affect the internal pelvic organs and can lead to infertility
But if diagnosed early and treated properly the damage can be prevented.
So you once consult gynecologist and get examined to find out the possible cause for your problems.
You need one ultrasound
to find out the causes leading to irregular periods
With your doctor's advice go for thyroid
profile once to rule out that factor.
