If your pregnancy test is positive, then you are most likely pregnant. You can request an ultrasound to confirm a normal pregnancy and to exclude a few rare conditions (ectopic pregnancy, molla etc.). An ultrasound is also diagnostic confirmation of a positive pregnancy test result (more reliable than a urine analysis). Pregnant women have increased vaginal discharge. In your case, it seems that a vaginal infection must first be excluded. You can follow up with both examinations at the office of a gynecologist.
