I'm asking for a friend. My friend had sex 4 times since her last period. She's usually very regular. She doesn't think she's pregnant because they had sex like they usually do with condoms, and he never cums in the condom and it's worked for them for a year now. Her period is 5 days late now, she's had some cramps like always and feels like it's gonna come soon. She thinks that it's just because she's been stressed but is there any chance she could be pregnant?
