Had sex 6days before ovulation, could i still get pregnant? currently 7dpo

Sure: It is always very difficult to accurately predict exactly when ovulation occurs. If you do not want to be pregnant consider using condoms or birth control

Slightly possible: There is about a 3 out of 1000 chance of conceiving by having sex six days before ovulation.

Unlikely: but "possible" Sperm can survive in your body for about a week however probably not in numbers sufficient to fertilize an ovum ( a number of sperm are necessary) Use a "safer" form of birth control if you wish to avaid pregnancy. Good Luck Hope this helps Dr Z
