10 DPO BFN :/

Massy • Mommy of preemie twins born at 29 weeks with IVF fresh transfer
Ok so according to countdown to pregnancy.com I am 10 DPO today and I decided to test with a first response Gold at 7 pm tonight. Like always I got a BIG FAT NEGATIVE !!! :/ :( ??????????????? the only reason I decided to test was because I've been very nauseas today and slight cramps. 
Can it be too early, according to glow my expected period is today or tomorrow :/ will test again on Saturday. ????✨??
Keeping my hopes high still .... Baby dust to all!
