Thanks for your query.
At a gestational sac
of more than 20 mm, a foetal pole should be clearly visible.
At five weeks of pregnancy
, yolk sac
is also seen.
THe spotting with pain is also not normal.
is correctly prescribed for pregnancy support.
YOu should take rest, avoid stress/exertion/intercourse, and go for regular follow up as advised.
Chances are you might abort this pregnancy, or in certain cases, if conception is delayed, it might still grow on normally.
By 6 - 7 weeks of gestational sac size ( approx 20 mm ), if there is no yolk sac/fetal pole/cardiac activity, then pregnancy is definitely non viable.
take care and all the best.
