Thanks for the query.
I understand your symptoms. This is a very normal phenomena associated with menstruation
. It should be gone soon.
If it persists even after your menstruation is over, then get an ultrasound
of the pelvis region to check for any abnormalities in the fallopian tubes and ovaries.
Meanwhile, drink plenty of water and take adequate rest.
Mostly, you will be fine in a week's time.
