Hello and welcome to HCM,
Whitish discharge per vaginum is called leukorrhea
Small amount of vaginal discharge
is common in healthy women.
An increase in quantity and/or change in physical and physical charateristics of the vaginal discharge is called leukorrhea.
The various causes of leukorrhea are:
1. Infections of the genital tract especially cervix
2. Congestion of pelvic organs
3. High estrogenic stimulation
4. During sexual excitement
5. Early pregnancy
White discharge admixed with blood may be due to onset of menstruation
or due to rupture of hymen
(if there is a history of trauma as in your case).
Hymen may have ruptured in case your movements caused such an impact on the hymen.
It is difficult to confirm a rupture without examination.
Thanks and take care
