brown discharge again, no blood?

Hi,
Welcome to ehealthforum.
Brown discharge or spotting in between periods could be attributed to the hormonal contraceptive use, breakthrough bleeding, other hormonal derangements, endometrial hyperplasia, endometritis, ovarian cysts etc. 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). The urine pregnancy tests done very early in pregnancy can show you false negative results as the kits are calibrated ones, so unless the hormone levels in urine reach a certain level, they do not show positive results. If pregnancy gets ruled out, further evaluation would be done to look for the underlying cause for your symptoms. Treatment as appropriate (based on examination findings and investigations results) would be started to help you control the symptoms and regulate your periods. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet and lifestyle.
Take care.
