Pregnancy Question

Brookelynn

I’m 35 days late, and I’ve had boob soreness/sharp pains in them for the past three weeks. I’ve been nauseous every day, and my temperature is very irregular. I’ve taken multiple pregnancy tests that I peed on, and they are all negative. Could I be pregnant, and it’s not showing up on a urine test? Are these symptoms of something else? Please tell me if you have experienced this. Thank you!!
