Is it possible to test too early?


I track when my due date would be on a “pregnancy calculator” online,thinking I would get pregnant that month! So I put my first day of my last cycle in and read the “conceived” date as 1/21. GLO says ovulation was 24/25. I tested on Thursday 1/31, got a negative. I did the baby dance the 20th (day before online calculator predictions) & the two dates GLO predicted. So was 6 DPO for GLO’s prediction too early to test?
