Have just taken my first ever OPK

[Apiarist]

It was positive. I thought that meant that tomorrow was peak DTD time but I fed the info into my fertility app and app says yesterday was best day.

Now I'm

Can anyone enlighten me?

I would guess that as this is your first opk your app doesn't know your cycles well enough to predict yet. Generally you ovulate from 12 hours after your first positive but it can be up to 72 hours later, although I think it is generally normal to be between 24 and 36 hours later.

What kind of OPKs did you use? I would dtd tonight and tomorrow. I am currently 11 weeks pregnant after dtd the same day as my first positive opk...

[Apiarist]

Damn. Tonight's not possible (DH on a trip).

They were True ultra sensitive strips & this is my first Clomid cycle (unmonitored).

It would good to grips with it all this month if only to be more confident next month.

I should have started testing a couple of days ago maybe?

Anyone else?

Are you in the middle of ypur cycle?

[Apiarist]

Day 13

Then I would imagine ovulation will occur tomorrow. In the past when I've used opks I get ov pain 24 hours after the positive opk.

I can't advise you but saw something about this fertility app earlier this week.
You could use it to know your fertile time.

Sorry if this is irrelevant.
Good luck.
