I have PCOS/PMOS. Why are my periods light this time?

Question

Hi doctor,

I was diagnosed with PCOS/PMOS about two to three months ago during a sonography and was prescribed Blurin tablets.

I had intercourse in the first week of this month, and after three days, I experienced vaginal itchiness along with a white, milky discharge that lasted for several days. I also used a Prega News kit 10 days after intercourse, and I was not feeling well during this time.

Currently, I am on my period, but I have some doubts. The first bleeding appeared brown in color and then turned lighter than red. Today is the second day, and although there is bleeding, it is not as heavy as before. My last period was at the end of the previous month.

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

You have PCOS (polycystic ovary syndrome), now known as PMOS (polyendocrine metabolic ovarian syndrome), so your cycles can be a bit irregular, and the bleeding pattern can also look different - brownish at first, lighter flow, and sometimes not like before. That itself can explain why this period feels unusual.

The white milky discharge and itching after intercourse sound more like a vaginal infection, most likely yeast or fungal, and sometimes mixed with bacteria.

You already took Oflox-OZ (Ofloxacin and Ornidazole), but that is not the first-line choice for vaginal infections; usually, antifungal medications or local treatments work better. Since you have already gotten your period now, pregnancy is not a concern, and your negative test result also supports that.

The probable causes are PCOS/PMOS affecting your cycles, along with a vaginal infection, most likely candidiasis. If the discharge persists, a vaginal swab for culture and microscopy should be done.

A repeat ultrasound may be considered if cycles continue to be irregular, and a hormone profile including:

FSH (follicle-stimulating hormone).
LH (luteinizing hormone).
TSH (thyroid-stimulating hormone).
Prolactin, and
AMH (anti-Müllerian Hormone), if not already done, would also help in evaluation.

Possible conditions to consider include yeast infection, bacterial vaginosis, mixed vaginitis, and normal cycle variation due to PCOS/PMOS. The most likely diagnosis in your case is irregular cycles from PCOS/PMOS with a vaginal infection.

Since you are currently bleeding, pregnancy is not a concern. For the discharge and itching, you may need an antifungal tablet or local vaginal cream, but this should be prescribed after a direct check-up.

In the meantime, maintain proper hygiene, avoid tight clothing, and keep the area dry. For PCOS/PMOS, continue the medicines advised by your doctor and focus on lifestyle changes such as regular exercise, maintaining a healthy weight, and reducing sugar intake.

If the discharge and itching continue after your period ends, it is better to follow up for a local vaginal examination and appropriate antifungal treatment. Also, make sure to have regular follow-ups for PCOS/PMOS treatment with your gynecologist to keep your cycles under control.

Preventive measures include safe sex with protection, wearing cotton undergarments, maintaining good hygiene, eating a balanced diet, and reducing stress, as this helps with both PCOS/PMOS and hormonal balance.

I hope this has helped you.
