Hi there...first thing is to go for home pregnancy test if positive you should not take self medications because there will be no guarantee for complete expulsion of fetus,and if the fetus is developing in fallopian tubes you can rupture of the tubes....ultrasound helps to confirm abdominal pregnancy and complete abortion,retained product may cause sepsis and hemorrhage....if negative Consult nearest gynecologists for evaluation they will do the needful.

First thing to do urine pregnancy test...second  ..visit the gynac though positive or negative
