So aggravated!

According to glow AF isn't due till the 19th. But last month it was almost a week late for some reason and due to 2 ectopics and 4 surgeries it's been all over the place the past 6 months. So I started spotting dark brown 3 days ago. It stopped and then started again tonight, not any heavier and not really bleeding, just super thick sticky almost black discharge when I wipe. I've never had spotting before AF before. I'm also kind of crampy tonight but not sure whether that's actual cramps or just plain exhaustion and dehydration from a very long hot work week cuz my whole body is kind of crampy and I'm exhausted. I'm not even really sure what I'm pissed about right now. Mostly just sick of this crap every month. With this spotting I really want to believe it's implantation bleeding, but with my periods all jacked up I have no idea if I even had my ovulation time frame right. And if it's not implantation then why do I feel like crap so early before my period?! I just had the surgery to remove a huge uterine septum and lots of scar tissue and my dr believes that and a blocked tube were the cause of my infertility issues, so I should be relieved and excited but I'm not, I'm just stressed out and tired of trying and really not caring anymore. And if this is AF I wish her stupid ass would just hurry up and start already so I can quit feeling like death! Sigh.... Ok im done whining now.
