Pregnancy report was positive with one dark(c line) line and one slight line(t line) on 20/07/18. On that day on TVS no gestational sac was seen in the uterus. So i do beta HCG test on alternate days. 20/07/18 1st test showed540 mIU/ml next 22/07/18alt day test shows 965.6 mIU/ml om repeating USG on 23/07/18 a very small gestational sac was seen in the uterine cavity. On checking no obvious gestational sac was seen in the tubes or overies or adnexa. Last period was on 15/06/07 n we go for intercourse on 03/07 and 05/07/18. Now question is it uterine pregnancy or ectopic pregnancy and what should i do?
