spotting blood along with white discharge, negative hpt?

Hi,
Welcome to ehealthforum,
The symptoms that you describe with lighter and altered periods along with increased vaginal discharge could suggest pregnancy possibility. The pregnancy tests done very early in pregnancy can show you false negative results unless the hormone levels reach a certain level. Look out for development of any other new symptoms if pregnancy is suspected. If periods do not start within 10 days of expected period dates, or if you have got abnormal periods, or if you suspect chances of pregnancy, consider visiting your doctor/gynecologist at the earliest for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). Your doctor/gynecologist may repeat the blood beta HCG test after 10 days or consider taking an early ultrasound scan to confirm/rule out pregnancy.
Take care.
