The white discharge in pregnancy
resembles the ovulatory discharge and is not thick. Thick discharge may be due to estrogen
and if associated with itching or burning, could indicate infection. If you have been taking basal body temperature
throughout your cycle, ovulation would be indicated by a sudden spurt and this would persist if conception has occurred. The earliest way to confirm/exclude pregnancy is by getting a blood test
done about one week before your next period is due. Hope your query is answered. Take care.
