My partner and I had protected sex using a condom, and I did not ejaculate. Later, I fingered her, and while I don’t recall clear semen or precum on my fingers, there’s a slight chance there may have been some. There was no penetration without a condom. She is now over 2 weeks late on her period, and this was her first sexual experience. We’re concerned about the possibility of pregnancy despite taking precautions. Could the stress of the situation or it being her first time delay her period, or is there a real risk of pregnancy? Should we take a pregnancy test or wait longer?
