Hello, thanks for using health care magic. Abnormal bleeding in any sexually active female warrants that a pregnancy be ruled out first. This will require you do a home pregnancy test with urine. If its positive, then you will need to urgently to an ultrasound to get the location of the pregnancy and the viability and gestational age. However, other possible causes such as infections, fibroids and abnormal and rapidly growing cells at the cervix could cause similar symptoms. So, do the pregnancy test immediately and then meet a doctor for detail evaluation and management. Best regards Dr Achuo
