OPK test


so I got 2 positive OPK tests this month one on CD 10 then they all went complete no test line negative after that so I was like okay cool we had db stop testing for some odd reason today my boobs are sore and I'm a little cranky plus slight cramps I did another OPK test it was strong positive am I double ovulating like I did sometimes when I first started AF or is it a fluck?
