Symptoms...?

I'm 9dpo and tested this morning. Got a bfn. I know it's early. I have just had some weird symptoms. Due af 7 Jan. Super sore boobs for the past couple of days, really emotional (I broke down crying this morning for no good reason) and feeling sick on and off, worse at night. Does anyone else feel like this? Did it turn out you were pregnant? Is it maybe just af going to arrive early? Please help, feel like I'm going crazy here lol :-) Happy New Year to you all xXx
