please doctors in the house,I had an issue with a lady here in abuja who claimed tone pregnant for me..I was alarmed when she presented me with a test result dated 26th of September and a scan result dated 25 of November and it read she is 16 weeks and 5 days pregnant.
by virture of my job, I travel a lot, I left abuja around 1st week of June and came back on the 20th of august and she visited 5 days later
so after calculating the date the duration is way over the date given by the scan..please guys advice me,is the scanning process not that accurate enough to accertain the duration of a baby in the womb? and if its in accurate what is most likely the percentage variance in error?

At this stage of the pregnancy, scan is very effective in estimating gestational(pregnancy) age with only few days margin of error.

Also ask her the last time she saw her period and then discuss with a doctor to ascertain the correct date.

.....on a lighter note, why not use raincoat if you no fit hold body..... remember say as you de deposit na so you fit withdraw the other one oo
