ShereeJoy,
Every other day means every second day. This is often what we tell ivf couples too. It gives sperm a chance to regather! Gives the couple a rest and does not seem to impact on conception. In fact studies show it gives a better chance. Having said that we dtd every day around ovulation - but my dh does not have a sperm issue and I went with my gut. So that's a choice for each couple to make.

OPK"s are strange beings. Basically the LH surge occurs 12-48 hours before ovulation. It is this surge that triggers ovulation to occur. So, for example if you test at 2pm daily (thought to be the optimal time - though many ivf specialists will suggest a morning test) and you get a positive that test could have been positive at 10pm the previous night (it is usual for a surge to last 24hours) so you are never certain when the surge occured. This is why it'simportant to test at the same time each day. Then get jiggy with it as soon as you see a positive (or that night!). This gives you optimal chances of fresh sperm waiting for your egg. Studies show that having sperm waiting when ovulation occurs gives you the BEST chance of conception. That is why the second daily regime is a good idea around ovulation time. Many women will see a fade in pattern where there previously clear opk sticks start to get a second line. If this happens to you that's great and it would be when I would begin the second daily dtd regime.

Women's ovulation isn't static - many things can affect it so it's not a good idea to just rely on what you "usually" do if you are ttc. That is where opk's can be helpful. Remembering that many women will not get a true positive opk. Sometimes testing a few times a day is a good idea (this certainly helped me). So around 10am, 2pm and 7pm seem to be good times - around when you believe you usually ovulate (obviously just prior to when youbelieve youusually ovulate!).

I know for me I would get a darker line at 2pm and a true positive at 7pm sometimes. So, had I relied only on the 2pm I would have thought that my surge was yet to happen. But doing the extra test helped identify the surge. Remembering a line almost as dark is a very good indicator that your surge is about to happen so go for it then!

I hope that helps.
