If i had unprotected sex on ovulation but the sperm didn't ejaculate in me, should i worry?

Unprotected sex: Any time you have vaginal penile penetration wether you believe ejaculation occurred or not , you're at risk of becoming pregnant. Sperm can be transferred before ejaculation occurs. Protect yourself from unwanted pregnancy & sexually transmitted infection if you're worried about pregnancy. Otherwise i'll be happy to have you in my prenatal clinic if this is one of your choices. Thanks & be well.
