Ovulating twice?? Please help!!

Allysha

So on 07/15/2018 I thought this test was positive after I took this I got a negative the next day. We had baby danced shortly after the positive. Today I just out of the blue decided to take an ovulation test and this is positive (picture of test from today in comments) did I just read the first test wrong or am I ovulating again??? Been having cramps and pinches the last couple of days on my left side.

This is the test from 07/15/2018
