8 days missed period and 3 negative tests...

So, today is Day 8 of missed period. My husband and I have been trying to get pregnant for 2 years now off and on, but more seriously in the last year. My doctor isn’t super helpful and I actually had a scheduled pap today. So I mentioned it to the nurses and said I have already peed on a stick 2 times and both negative. So she had me pee on a stick again today and it read negative. My period is NEVER late - always early or on time! But 8 days late is a long time! Hah. Could I be pregnant even though doctors office pee stick said negative? They did blood work for my pap, I’m not sure if they can use that to check if I’m pregnant. She didn’t seem as concerned as I was that I’m 8 days late, so I thought I’d come to y’all! I’m overwhelmed by google 😊 Symptoms: headache, tired, slight cramping a couple days ago but it’s passed, boobs feel heavy, slight nausea in the evenings but starving in the mornings. Anyone else experience this? I don’t want to get my hopes up! But need some advice.
