Highly unlikely you are pregnant if you had intercourse the day your period ended. Not enough time for an egg to develop and ovulation to occur.
White discharge is normal in both non-pregnancy and pregnancy cycles. If you just ended you period a week ago, it's probably too early for pregnancy symptoms at this point.
Could white discharge be a sign of pregnancy? I had sex with my husband last saturday, (a week ago yesterday) and I started having this white discharge today during sex. Is it an early sign of pregnancy?
That depends on how long her periods are and how long her cycles are. Usually, chances are less at the end of her period than later in her cycle....but it is definitely possible.
