Am I pregnant ?

Ok so I started my last period on August 22nd and I ovulated on September 5th. I then started to have very light brown spotting for two days with a bit of cramping and bloating so I thought it was implantation but that seemed a bit early. Side note: my period is usually fairly heavy. I then kept having quite a bit of bloating and nausea along with headaches and was extremely fatigued. It’s now the 19th (the day I’m supposed to start my period) and I have yet to get a positive pregnancy test. This is my first time ttc and I’m so anxious for a positive. I took a FRER, Clearblue, and two cheap Walmart test this morning at 5 AM and they were all negative. Is it normal to not have a positive test by now? How far along were you when you finally got your BFP? I’d appreciate any input.
