A vaginal ultrasound can tell how far along you are. Also a blood test for HCG quants will tell also. Consult your doctor or clinic. It doesn't matter whether or not you have a vaginal ultrasound or one on the abdomen ultrasound is a very good way of seeing how far along you are in pregnancy and making sure that the fetus is developing accordingly if they see any problems in the development they will want to run more tests hope this helps you , Good Luck and God Bless!!!

Would an ultrasound be able to tell the difference between a fetus at 4wks3days and 7wks3days from conception your scan showed a faint flicker of a heartbeat which date is it more likely to be?

How early can you determine the sex of your baby?

You can probably see the sex of the fetus by three months. By then organs are already developed. However it is not easy to tell on some babies.

An ultrasound is, after the 20th week of pregnancy, generally more than 90% accurate at being able to tell a baby's sex.
