My bf tried fingering me,although he never finished he just rubbed the surface.he also might have gotten a little precum on his hands but he rubbed them on the sheets during the process. ive been seeing a few pregnancy symptoms like weeks after.why?

Observer Bias: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result if done correctly. One can test about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. An Ob-Gyn doctor can evaluate any persistent or worrisome symptoms.
