Ovulating 6 days after period??

S

So my period ended September 3rd and this is my first time tracking my ovulation with an opk. I had negative readings Thursday and Friday. Tested this morning at 7:00 am and got a positive then tested again at 1:00pm with another positive. I'm only 6 days out from last period and all three of my apps don't have me ovulating until the 13th or 14th... could I really be ovulating this soon??

TIA!
