Further along?

Kim • TTC #3 since March. Have a baby girl born March 2013. Baby boy born March 2016.

I took 2 tests today. Both clearly positive in a matter of seconds. I’m only 8 dpo. My question is: could this mean I’m further along? I had a period last month, but I know some women can still get it. Has this happened to anyone? Either strong positive so early, or turned out to be further along? Thank you!
