feeling queasy, I have more discharge than normal

Hi,
Welcome to ehealthforum,
If you have not been regular with your birth control pill intake, have taken them late by more than 2-3 hours than the schedule time on more than 2 occasions, you will not remain protected (the efficacy of the birth control pills will get affected). If you have had unprotected intercourse, chances of pregnancy cannot be ruled out. The 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 you suspect chances of pregnancy, you should consider visiting your doctor for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest.
Take care.
