Too early to test?

[A2026]

I had sex on the 20th December. Would it be too early to take a test? My period isn't due until 11th January

Are you tracking ovulation? How long is your cycle usually? Ovulation is generally 12-16 days before your period is due (14 days before for a 28 day cycle) so you may have dtd before ovulation. If you are not due until 11th January you may have missed your fertile window.

28 day cycle usually.. had sex on the 20th and 28th, hoping there's a little chance I conceived on the 28th and test when I'm due my period 🤞🏼been tracking and 28th was my highest fertile date.

You have a chance with dtd on the 28th, but too early now to test. I’d wait until 6th/7th at least, but probably best to wait until AF is due.
good luck!
