What could cause an 18-year-old girl to have irregular periods with lower abdominal pain and spotting?

Hi,

Welcome to icliniq.com.

If you have irregular cycles, it is better to check for a reason and have treatment for that.

1. Confirm that you have no pregnancy (otherwise check the blood pregnancy test beta hCG [human chorionic gonadotrophin] to confirm).

2. Have you checked for abnormal hair growth and sudden weight gain?

3. Take the tablet Primolut N (Nor-ethisterone) 10 mg 12 hourly for seven days and then wait for ten days to have a withdrawal bleed.

4. On day two of bleeding, I suggest you to take blood tests (serum testosterone, serum progesterone, serum insulin, serum prolactin, FSH [follicle stimulating hormone] and LH [luteinizing hormone] ratio, thyroid function test).

5. I also suggest taking one transvaginal scan outside menstrual days.

6. Collect all laboratory reports and you can discuss them here or local gynecologist.

7. Exercise daily with yoga and maintain a normal BMI (body mass index).

8. Eat a healthy diet.

9. If you want to regulate cycles by taking Cocp (combined oral contraceptive pill) you can take it for two to three months.

10. You are a teenager and your body is still in a developing state. In some individuals years after puberty, anovulatory cycles can be regular or irregular and then gradually ovulatory cycles.

11. It is better to check with investigations.

I hope things would be better.

Best of luck.
