Re: This doenst sound right to me.....
obviously an online calendar can not know you, nor predict your ovulation. it is merely a tool that you can use or not, but does NOT unsure accuracy. to do this you have to get in touch and familiar with your own body and cycles. there is a book called 'taking carge of your fertility' by toni whelcher (i think i spelled the last name wrong) that will teach you everything you need to know in that department. i guess several members here have used it and it had worked wonders. Blastoff knows more than me, maybe she will respond!
