Who is my baby dad? person a- 4/21-4/23 unprotected & plan b was used. started ovulating the 21st. person b- 5/1 unprotected no plan b. according to the first day of my last period i should be 5 weeks and two days pregnant which aligns with a?

Plan B is usually effective if taken within 48-72 hours of exposure. Early estimates of pregnancy are often off by several weeks. A NIPS test on maternal blood as early as 8-10 weeks can detect fetal DNA and provide test results that can confirm paternity. When more than one male is involved it becomes a legal issue where speculation often ends up with a worrisome surprise.
