Really would like some input .

Ok I really need some opinions right now. I took a pregnancy test back on 11 th July and got a positive test. I was not expecting the positive results since the closest thing I’ve had to period was at the beginning of the month on the 3rd I spotted a couple days but not really a full bleed. But didn’t think much of it at the time because I have PCOS and figured my PCOS was affecting things . Especially since the month previously I never bled. All I can assume is that me bleeding from beginning of the month was a period and I ovulated at some point and didn’t realize. The only thing is is that when I took the test on the 11th it came out extremely positive like as soon as the test started to run, it showed positive right away . I assumed that I probably been pregnant for a bit and so that’s why it was showing such a blaring positive. But out of curiosity today July 31st I took another pregnancy test, and the test still showed positive as soon as it started to run. But it definitely seems way lighter than the one I took on the 11th . Because of this I’m wondering is it possible for there to be so much hcg in my system and it’s been quite a bit of time since the first test is it possible that it can seem lighter because of that. Only asking because I’ve dealt with miscarriages in the past and I’m just wondering if there is any possibility that’s probably that instead of it probably being another miscarriage .
