So this is for fun!
I can guess what you're having based on the Ramzi Method http://hcp.obgyn.net/content/article/1760982/1878451
***Please note that I am NOT a sonographer nor am I ANY kind of expert by ANY means. This is strictly for fun and I will give you my best SELF educated answer****
Heres some simple suggestions to make things quick and easy=)
* Post your u/s from 6-9 weeks
* Please post if it was a transvaginal (meaning internal/dildo u/s), or an external (on the belly).
* To get the most accurate guess, it should be VERY clear in quality with as little "lighting" flaws as possible
Even if youve already had your LO and would still like to try this theory for fun, feel free to post!
Im interested to see how accurate this is so have fun!
