Has anyone tried the mom junction gender calendar?

Has anyone tried it and had accurate results? According to a few women I’ve talked to it’s been correct for them.

You have to put your DOB and date you conceived. I had to use a conceive date calculator since I wasnt sure and got a BOY result which I hope is incorrect because we really want a girl.
