Thanks for posting your query.
I understand your distress and confusion. Don't worry, as it looks like a delayed conception.
The pregnancy in itself should be fine, even though it is what we call as a delayed conception.
By your dates , you may be 6 or 7 weeks but date the pregnancy with the earliest scan where we see the baby. The earliest baby can be seen in transvaginal scan is at 5-6 weeks.
Even before the baby can be seen on the scan, we can see the yolk sac which is the structure feeding the baby. That appears on scan around 4-5 weeks.
So everything is going by plan in you case. So do not worry yourself.
We can wait until the
gestational sac is 25 mm before we call it an empty sac/
blighted ovum.
The early
pregnancy cramps are very common and are due to the bodily changes and hormonal effect.
I would suggest you repeat a scan in 2 weeks when everything will be clear. There is more than 90% chance that you will see a baby with a heart beat in that scan.
Please continue
folic acid,
duphaston is optional as its not helpful.
Hope this helps, take care!
