Confused!!

SE

Had three days of light period. I wanted to start my OPKs today’s since my period ended today so I did one and it was super bright and I thought that was kind of weird that it would already show that my LH levels were super high. So I took a pregnancy test and this came up..how could this be possible?!?!

Edit: I haven’t had a period in six months! (doctor said I needed to INCREASE fat in my diet$ And I have been getting routine bloodwork, two weeks ago my RE said that it look like I had finally ovulated. I didn’t really think anything of it. And obviously was pretty bummed when I started bleeding but relieved that I had finally gotten. But maybe this isn’t the case!!

I’m very worried that it is a chemical pregnancy because I have been bleeding..
