Help! Its long but please read 🙏🏻😫😫🙏🏻

August 15-19 - Testing with home pregnancy tests - All Negative 

August 20- Spotting (I assumed period was beginning) 

August 21- Spotting 

August 22- Spotting ends (Confused as to why I had such a short and light period) 

August 26- Positive pregnancy test

August 27- Positive pregnancy test 

August 28- Positive pregnancy test 

August 29 - Drove to Canada for Vacation

September 1 - Bought no name brand hpt in  Canada, took it, Negative pregnancy test 

(I didn't leave the stick in as long as I should have by accident so I was convinced I did it wrong and would test tomorrow) 

September 2 - Bought test, couldn't wait to test until morning, drank a bunch of water to pee, negative result....... Convinced myself it was negative because my pee was basically just water. 

I haven't been able to buy more tests because there is one store in the town where my cabin is and they've run out of tests. I had a miscarriage at 4-5 weeks back in December, I bled for 1 month. So if I lost this pregnancy, why haven't I bled? Is it possible this no name brand couldn't detect my levels? Is it possible they are both false negatives due to me testing wrong? I keep reading about Chemical pregnancies where one day its positive and the next day it's negative and then you get you're period. But I haven't bled or had cramps! Can't leave Nova Scotia for another 4 days. My husband says we should just wait until we go home to get another test. 

I'm freaking out. Any advice or thoughts would be appreciated. I just want to know if I'm pregnant. Or if it literally just disappeared out of thin air.
