Occasionally, few days before period, some little spotting to scanty bleeding is known. This is no way abnormal if it happens once in a blue moon. This is due to the waning of the hormones Oestrogen and Progesterone
form the body system before the period starts. Since the lining of the uterus
is maintained by these hormones, when their levels fluctuate, such spotting may take place. Usually within 4 days if such spotting, menses start.
If it continues to happen every time or you do not get your menses and spotting continues, you might have to report to your Gynaecologist for any investigations if required.
Age of the woman plays an important role in such menstrual variations. I would have appreciated to know your age. If you are approaching your menopause
or are above 40 years of age, such variations are known. So long as it does not become bothersome or there is no alarming type of bleeding, you may ignore it.
Now, for this cycle, just wait expectantly for your periods to appear. No treatment is required if you get normal periods within few days; if you do not, please report to Gynaecologist.
I hope this helps you.
