In the current scenario, you should get serial serum beta-hCG estimations than a single one since doubling titres every 2-3 days mean a positive pregnancy
progress, while falling values suggest some complication. You should also get a pelvic/trans-vaginal sonogram to locate the gestation sac and look for any hemorrhage. If there is a uniform-contoured sac without any internal hemorrhage, if the fetal pole
can be seen most often with a fetal heart, it is a welcome sign. Please take absolute bed rest
and avoid all stress
including intercourse and get help from your consultant. Take care.
