27 DPO 13 days late with BFN

I took another hpt and it came back negative again. But my nipples are sore and have been for a few so that’s another symptom added to the list. My boobs have been swollen I had to keep adjusting the band on my bra. It went from the last tightest notch to now being on the third notch. Nausea has subsided but I find that my sense of smell has intensified. Some food smells make me sick to my stomach. At this point I don’t know I’m losing it or if those hpt are crap.
