Brief Answer:
Your last periods were before Christmas

Detailed Answer:
Basically I have calculated your last menstrual period from this as 18th of December
but since ovulation occurs after 14 -17days of start periods so you must have ovulated around 3-6th of January
And since it takes 14-16 days for pregnancy to show up in tests, it was a negative test on 16th January
So I hope I'm clear on this but in case you need help please feel free to ask
