So Confused

Whitney
My period was august 11. According to glow it should have came September 8th. It didn't so I waited to see if it did the 11th. Nope. Then the 13th, I took a test and bfn. That night I woke up had a HORRIBLE cramp, went to the bathroom and started spotting. Then I got really really hot all of a sudden and started sweating and felt like I was about to puke. I got up to leave the bathroom and I blacked out and hit the floor. I thought maybe I was getting sick and starting my period. I spotted for 4 almost 5 days. Only when I wipe. Not constant like period. Not enough to fill a panty liner. I've been dizzy since, queazy feeling in stomach since, i almost puked when someone had cheese. I've been bloated on and off weird muscle aches and peeing more. No signs of af is coming. So I bought a frer test and took it and bfn. Then today I went to med express and did a urine Test and bfn but the Dr said it could be too early. How long do you think it would normally take to show up? I have a gut feeling that I am pregnant but can't get tests to prove it so I'm not calling that a "symptom"
