I appreciate your query.
The B- HCG test is positive very early on in pregnancy.
As far as ultrasound is concerned, various milestones are seen at varying time intervals.
The gestational sac(GS) is the earliest sonographic finding in pregnancy. It will be slightly difficult to see if the mother has a retroverted uterus or fibroids.
In case of ectopic pregnancy, the GS is not seen inside the uterus.
The GS is identifiable until approximately 4 1/2 weeks only with a transvaginal scan.
The yolk sac appears during the 5th week. It is the second structure to appear after the GS. It should be round with an anechoic centre.
Failure to identify (with transvaginal ultrasound) a yolk sac when the gestational sac has grown to 12 mm is also usually indicative of a failed pregnancy.
A mass of fetal cells, separate from the yolk sac, first becomes apparent on transvaginal ultrasound just after the 6th week of gestation. This is called the fetal pole.
This is when the cardiac activity ( heart beat ) is seen too.
Absence of either ( fetal pole or heartbeat ) beyond 6 - 7 weeks of pregnancy is indicative of failed pregnancy too.
These parameters are seen on transvaginal ultrasound ( TVS ) only.
If you had an abdominal ultrasound, these details might not be seen easily in early pregnancy.
Also, if the ultrasound was done around 4 or 5 weeks, it is highly possible that the cardiac activity is not seen still, which is normal.
But the problematic symptom is having very dark brown spotting.
It could mean an impending ( threatened ) abortion ( miscarriage ), which is the commonest possibility.
If an intra uterine sac is seen ( pregnancy is inside the uterus ), you need not worry, as sometimes this kind of bleeding occurs with ectopic pregnancy ( pregnancy outside the uterus )
Sometimes, although rarely, such bleeding occurs with a totally normal ongoing viable pregnancy.
Only a repeat ultrasound will tell you the real diagnosis.
By now, you must have completed 6 weeks of gestation, so a sac with fetal pole and cardiac activity on TVS should be seen
With the kind of spotting described, you should not wait till 15th of January.
Please go for a repeat check up.
The soreness in the back , fatigue and tiredness are all part of the symptoms of early pregnancy.
Take enough rest, abstain from sexual activity till your doctor allows you and have plenty of fluids, a healthy diet and prenatal supplements as advised.
All the best and do post your further ultrasound reports etc. for further clarification.
