Ovulating very early and short cycles - help please!

Hi everyone,

I need a bit of advice please. According to my easy@home OPKs and Premom app, I reached my peak twice in the last three days - once on CD7 and again yesterday on CD9. Premom is estimating my cycle will be 21 days this month but its normally 28 days. Am I right in thinking this isn't conducive to TTC because the egg wouldn't be mature on CD 7 or 9 (or around that time)?

Any advice appreciated!

If you are having multiple peaks it might mean you haven’t ovulated yet - you can check that the LH surge has actually resulted in ovulation by your BBT.

There is a study online which looked at ovulation and conception and there wasn’t any serious difference between early/“typical”/late ovulation and conception.

This is the study. The window for “typical” ovulation is CD10 - CD17. If you got an OPK positive on day 9 (and that causes your ovulation) then you might ovulate CD9-11

Sorry the typical fertile window is CD10 -17: ovulating before CD 13 was “early” in the study.

@Creatorofthepostinotes Thank you so much for your replies. I'm still a bit confused because none of my OPKs have been true positives - the highest this cycle being 0.85 on the T/C ratio on the Premom app and that was on CD7 (then went down and back up to 0.81 on CD9). Last cycle my peak was 1.98 so a huge difference. I'm now on CD11 and they have dropped considerably. Maybe I'm just reading too much into this.

I'll have a look at that study. Thank you for sharing the link and your knowledge of it with me.

How long have you been ttc?

I’ve always had short cycles, 21-24 days.

2 children no issues.

It’s all so confusing. I use OPK for the warning that I might ovulate and BBT to check I have.

From what I’ve read, it can take a couple of “attempts” to ovulate in a particular month. I don’t know enough about premom to know how accurate their readings are/can be influenced by hydration etc.

If you can bear to, I’d keep testing with the OPK until your usual ovulation time - just in case. Xx

@Nomoreusernames1244 this is only cycle 3 for us so still potentially early days, but it's great to know you've had two children despite a shorter-than-normal cycle!

@Creatorofthepostinotes thank you again. I don't track BBT, I don't need another thing to obsess over but mainly that I don't get up at the same time every morning. I was aware that if the body fails to ovulate it will 'try again' a day or two later. I am just mystified by the Premom scoring system (for want of a better phrase) and lack of true positive OPKs. I will continue to track as today as CD11 and normally I'd get my peak in the next 2-3 days so I need to just shrug this off and see what happens.

Good luck! Hope you get a really excellent OPK peak (one that keeps even premom happy) soon!
