Feeling uneasy :(

I’m 9 DPO and I took a FRER test this AM, and it looked like there was no line. I am feeling VERY nauseous (which is highly unusual for me), and I’ve had headaches and light spotting and cramps, but way lighter than my normal period cramps. I got so discouraged this morning from my test, but I’ve never felt this way before. Any ideas?
