Help on when is best to BD using fertility monitor

I'm currently using CB fertility monitor to pinpoint ovulation better so that hopefully we can catch the egg on 3rd month of TTC while still swaying pink.

I know the monitor will give me 3 high days, 2 peak , 1 high ( H, H, H , P,P, H)
I've read all 600 reviews on Amazon to see if I saw any people bd on 1 or 2 of these days but it seemed as if everyone DTD on most of those days ( not sure of the sex outcomes).
As for myself with my last pregnancy we DTD on most of those days and I conceived our little boy.
My question is if I were to pick 1 day which day is ideal for bd to achieve pregnancy?

My other question is if I chose 2 days which 2 would be ideal and still sway pink a bit?

I know 2 attempts wouldn't be ideal so close but I'm sorta worried like the last 2 months 1 attempt might not cut it.

I was thinking of bd the second high day in the am and doing another attempt on 2nd peak day pm.

I don't have any advice for you, but jumping into the thread as I am interested to know also. Good luck HealthyGirl! :)

Once I had been using my monitor regularly I nearly always ovulated on my second Peak day.
If you are going for one attempt the best days are O-2 & O-1 for conception. If you ovulate on your second peak day then BD the last High day or first Peak day which would give you O-2 or O-1.
I hope that makes sense.

I think if you go for second Peak day it could be too late. I would try first high & first peak.

That is because 99 out of 100 people are using a fertility monitor, well, for fertility. As in, they just want to get pregnant. Hence, they are having intercourse more than just once. :)

For TTC a girl you should BD on the first peak. It is best odds of conception that is easily determined, because while the high day before the peak is also good odds of conception, it doesn't always work out that you GET 3 high days and it is much, much harder to pinpoint than the first peak day is. (more about this below) If you must add in an attempt (and be aware that our success for pink drops between 10-15% with 2 attempts as opposed to one) then yes, the last high day and the first peak day. The problem is that you will not always KNOW when that high is there. Some people only get one high, or two, or get four instead, or even go straight to peak with no highs. Don't panic, just DTD when that first peak shows up. That one is the "money shot" LOL.

Thanks so much trueblue and atomic for the responses.

Groovynae are you using a monitor as well?

I got my first high today and know for sure I will have 2 other H days before the 2 peak. If bd on my first high and then first peak would the 2 attempts be categorized as 1 attempt or 2?

I think if you BD on first high, then first peak you would have BD twice in three days which would be 2 attempts. As Atomic has said above a second attempt drops pink success by 10-15%
Personally I think stick to one BD on your first Peak day and that's perfect :)

I used my monitor for a long time and you can't guarantee the number of highs and peaks you will get. Especially in your attemp month, if there's going to be a surprise that will be the month it will happen.
First Peak is perfect all by itself :)

I think by bd on first high and first peak the attempts would be 3 days apart.

Just sharing: I've never got highs with the monitor just went straight to the peak ones. And if if i had an extra trip to the bathroom the monitor wouldn't peak it up, when the other two different opks were positive and I had all the other signs approaching ovulation. Maybe back it up with smth. GL!

well, that's what I'm trying to say - you DON'T know you'll have two high days before peak. Some people are finding that the monitor gives one day or two days or even NO days of high before peak sometimes. Just want you to be prepared for that. What if you get one high and then BD and go to peak the very next day??

2 attempts will be two attempts.

If the attempt is not in your fertile window (or so far out that it has little to no chance of resulting in pg) then that may not count as an attempt. But two attempts in the fertile window is two attempts. 3 days before peak, yeah, that's pretty slim odds, but like we're trying to point out, there is no guarantee that will happen (and this can change even if you've used it in the past and always gotten 3 highs)
