Did I miss my window?

[donut8]

According to the app I use I ovulated on Saturday and we DTD on Sunday, have I missed my window? We weren't planning on starting to January so it was a last minute decision. I'm hoping the app might not be accurate and I'm still in with a chance. I had ovulation pains a few days before but I can't remember when 🤔

After your egg has been released theres normally around 10 hours window to fertilise it. So if you actually ovulated yesterday evening then dtd this morning may have just got it. Best bet when you do start trying properly is to dtd for a few days before you ovulate so theres a better chance of sperms remaining in your tubes from those (as well as dtd on the o day and the day or two after).
In short - yes theres a chance!

The apps only work on a calculation based on the average women so aren't 100% accurate so you never know you might have caught it

An app cannot know when you ovulate.
Are you using OPKs? The only way to know is to do ovulation tests x
