HELP!!!!

Sa

I started testing with my opk's the 2nd of this month my period ended the first up until now...I haven't had a positive opk....and this opk in the picture is from the one today....I've had a LH Surge up until this point...should I be worried? Ever since I was off my period me and my bf have been TTC....for the last 3 months....last month I received a positive OPK? Should I worry? Or have I already ovulated and never knew?
