Read through this article to ensure you date your pregnancy correctly !
The timing of your first scan is very important, so having followed the instructions in “Interpreting Pregnancy Test Results” section, you have arrived here.
The timing of the first viability scan is very important, the viability scan will show a heartbeat, that the pregnancy is developing in the correct place, how many babies you are expecting and also confirm your dates and give you an expected date for delivery of your baby or babies ! A significant scan for any expectant parents and one that you want to go smoothly. So arriving to see your Baby Scan Consultant to find that you have come too soon is very disappointing not only because you were looking forward to seeing your baby for the first time but also because of the apprehension about whether everything is going to be okay and that you will hear a heartbeat. This leads to upset and tears, no heartbeat, more anxiety as to whether it really is too soon or that there is no heartbeat because something is wrong and you have had a very early miscarriage.
So remember that when you take your pregnancy test on the first day of your missed period, you will be, according to how your Obstetrician or Baby Scan Consultant will date you, 4 weeks pregnant. This is ALWAYS assuming you have a regular 28 day cycle and ovulate on day 14.
Mr Penman recommends that as an absolute minimum, you must be 6 weeks pregnant for a heartbeat to be detected. A day either side of this may make a difference between detection of a heart beat and no detection. Ideally, Mr Penman would suggest a scan around 6weeks 5-6 days, so almost 7 weeks as a preferred time for a scan, if not a little longer, to avoid the upset and disappointment of a scan leaving more questions than it answers.
