A friend of mine had sex with her partner that is much older than her. She’s about 25 and he’s 40s or 50s, I can’t remember which. But, he’s had two vasectomies. She had sex with him the last day of her ovulation according to this app, and was suppose to have started her period on Thursday, and bs not started it. So she’s wondering, is there any way she could have gotten pregnant??? She’s been worried and asking me, and I would think she couldn’t be pregnant. Am I right or is that a possibility?
