Since you are not on any birth control, failure rates are more when using only the condom. If you were previously menstruating regularly every 28-30 days, your chances of pregnancy
are high. Since you are having an altered vaginal discharge
now, you should get examined by a gynecologist to see if you are suffering from any missed abortion
or a simple hormonal disturbance. You may need a blood test
for pregnancy and also a sonogram. Take care.
