Possibilities in your case would be some hormonal imbalance leading to intermenstrual breakthrough bleeding
as ovulation bleed is usually fresh. If you are not on any contraception
and are sexually active, you should also consider a pregnancy and get tested. I would ask for a urinalysis
, pelvic/trans-vaginal sonogram and observation to clarify the issue. If no local cause is found, hormonal status should be assessed, weight management
is done along with stress-relief, healthy diet and treatment of general infections. Hope you find this information useful. Take care.
