Totally confused?! 😞

The cycle before last we think I had an early MC. AF came 6 days early and was heavy bleeding/pooling and passing small clots for 5 days whereas usually my periods are medium/light with spotting towards the end for 4 days. Anyway my AF came a few days earlier than expected this cycle to. My cycles are usually regular and bang on date with what glow expects. This AF I bled for 1 day medium flow and then 1 day spotting. My CM has been totally different to usual to with it being EW right up to my period and I still have it now. My AF should have been due on Sunday but it had ended with barely spotting on Saturday. My initial thought was implantation bleeding but the blood was red, not pink/brown. Strange thing is I feel like I'm having a lot of early pregnancy symptoms even though my AF has been. I have Ehlers-Danlos syndrome and my first pregnancy I ended up in a wheelchair due to an issue I have with my SI joints and walking has been causing more pain than usual over the last 2 weeks. My breast are so tender when I remove my bra and stomach is cramping and bloated. I also suffer with chronic fatigue which has worsened over the last couple of weeks to. I've taken test tonight and it's negative but it's so strange actually feeling like I may be pregnant! Is my body just mocking me and feeling like this as I was to be pregnant so much? Or could my cheap tests just not be able to tell me yet? I was so hyped up feeling like this thinking it's finally happening after 19 month of trying and that bfn has burst my bubble. 😞 anyone has the same thing with symptoms and not BFP?

Thanks in advance for any advice x
