Am I pregnant or what? HELP!

Ok Ladies- I desperately need your opinions because I’m on my last hope for a BFP this month. I usually have a 30-32 day cycle but today makes cd37. I don’t temp, and I didn’t use opks this month but according to Glow I O’d on the 12th and I had ewcm on the 11th-12th so it makes sense. DH and I BD’d on the 11th, 13th, 15th, and 16th. Then on the 18th I had about an hour of pinky orange spotting that I only saw when I wiped (sorry, tmi!) followed by some light cramping. I was supposed to start my period on the 26th (cd 31), which I didn’t and that brings me to today,the 2nd (cd37). Symptoms so far have been sore boobs on and off, minimal cramping that comes and goes, fatigue, headaches,and backaches. Last night I encountered a bout of extreme nausea that went away after a few hours, but returned briefly this afternoon . I have tested a few times on frers, two of which I though were vv faint bfps but then the next morning I’d get a stark white bfn- so I’m not counting anything now unless it’s an obvious pink line. I realize I could’ve O’d later than I thought, but even if that’s the case and implantation DID happen- wouldn’t I see SOMETHING by now? I just want af to come if this isn’t my month. Be straight with me- am I totally out?
