My partner and i had intercourse on 12 of aug (unprotected) , but i finished outside her. Her period cycles is 29th of the month and it is generally a day off but mostly accurate She has tender breasts and lower back pain with a few crams and legs hurt too. What are the chances that she could be pregnant ? As it has been 2 days since her period due date We are taking a test but just wanted a professional opinion on this before we take the test.
