HI,
You have not mentioned your age.This type of bleeding is to be investigated,dignosed & treated in time.
If you are in a child bearing age-
- excessive
stress,physical strain, may cause it.
- impending
abortion -where there is unprotected sex in fertile period,May be the period was delayed.
-a small polyp at cervical mouth may cause it- here the bleeding mostly starts after sex.
- Few problems of urerus like
fibroid,
Hormonal imbalance is to be excluded.
-this is the time for investigations like
PAP smear.
In premenopausal age its common to have
irregular periods.( FUH)
In short, if it's first time,don't panic.,take rest & light-refreshing
diet, lot of fluids ( to normalize urine)bleeding may finish in a couple of days. you can take haemostatic drugs like citrus biflavonide compound with
vitamins C,& K. Wait for a couple of days.In case there is no response or if it repeates again, you need a Gynecologist's consultation& investigations & treatment.
Thank you.
