Having some trouble with ovulation chart

Ok my cycles are about 32-33. I have NO idea my luteal phase so I try the normal 14 and 16 which is half of 32.

1) On one site:
When I plug in my last period date and 32 cycle it gives me I am fertile between 9/13-9/18.

2) On another site:
When I plug in my last period date and 32 cycle (and 14 luteal) it gives me I am fertile 9/13-9/16. Ovulating on 9/16/10 but then states fertile again on 9/17/10?

3) On the same site as #2:
When I plug in my last period date and 32 cycle (and 16 luteal) it gives me I am fertile 9/11-9/14. Ovulating on 9/14/10 but then states fertile again on 9/15/10?

WHAT THE HECK!! lol


How can you be fertile the day after you ovulate?

Re: Having some trouble with ovulation chart

mmc has me being fertile the day after my predicted ovulation date. I think it's because the egg can live up to 24 hours (or is it 12?) so theoretically you can get pregnant the day after you ovulate.

Ok that would make sence then.

I guess I will just have to try almost every other day until the end of the month. lol this way I cover all grounds lol.
