Hi! No worries.

Many people believe that bleeding after intercourse is a sign of virginity because it proves that the hymen — a thin, fleshy membrane that partially covers the vaginal opening — "broke." 

But, not all women bleed the first time they have sex. Not only can hymen tissue simply stretch during penetration, rather than tear and bleed, but it is also very common for the hymen to rip before a woman ever has sex. Physical exercise, like riding a bike or doing gymnastics, injury to the genital area, or inserting a tampon, finger, or sex toy into the vagina can all cause the hymen to split. Sometimes there will be discomfort and blood when the hymen tears, or there may be no blood or pain at all. In fact, you may not even know when your hymen breaks.
