I feel like I’m having textbook pregnancy symptoms but no positive test yet

I’m 11DPO, CD 27, and 3 days until AF. However since right after ovulation and BD, I’ve had light tugging cramps in my lower stomach area, what I believe was IB at 6-8DPO (dark brown spotting and I NEVER spot), my boobs are very swollen, tender, and slightly darker, moods are kinda crazy, bloating, and lower backaches. On occasion I’ve had a metallic taste in my mouth and been more hungry than usual. I’ve tested the last 3 days and still negatives. I’m crossing my fingers its just too early to test, but I feel like I also wouldn’t be having this many symptoms during my TWW when it’s NEVER been like this for me 😔😔 anyone else have a similar experience?
