Am I getting my hopes up for nothing?

I have PCOS. For years my period has been very irregular, but in the last year and a half it has started to become pretty regular. Anyway, I am now almost a month late on my period according to Glow. I have a history of miscarriages, and pregnancy tests coming up negative even though I was pregnant. I don't have insurance so I can't go to the doctor until I am absolutely sure I am pregnant. I have taken 2 home pregnancy tests but the last one was over 2 weeks ago. I am waiting till next Wednesday which will mark 3 weeks since my last test. I know what day I would have gotten pregnant so I know this will make me just over 8 weeks pregnant if I am. Am I getting my hopes up for nothing? I have had 8 miscarriages in the past and not one of them was I aware I was pregnant until I ended up in the hospital because of a miscarriage. I feel differently than I did before, more sure, but I don't know if that is just my body reacting to how badly I want this.
