Even if your parents ARE very traditional and religious, the health of their daughter will be first and foremost on their minds. This may be a sensitive......perhaps even an embarrassing subject to discuss with your mother, if something is wrong, it needs to be found and treated now.
As to what they "might suspect," with your permission/consent or your request, the doctor can assure your mother that you are, still, indeed, a virgin.
I know this may be very difficult for you, but when it comes to your health, you must speak up.
I wish you the very best

Light bleeding/spotting between periods is very common and is usually just a small amount of blood from your last period that did not get expelled. It is usually kind of brown in color as it's "older" blood. If what you are seeing now is fresh (bright red) blood, I urge you to see a gynecologist. I would urge you to see the doctor either way to simply rule out any problem. If you use tampons during your period, there is some possibility they may be irritating your hymen. I wish I could give you a definitive answer, but only a doctor can give you a diagnosis.
