Positive ovulation BUT...

Hello ladies... this is my first time seeing both lines match... It looks positive to me and I'm happy just to think that I'm actually ovulating :) The thing is I took letrazole about a week and a half ago. Can that cause my test strip to be positive? Also, I'm scheduled for an IUI tomorrow morning and tonight I am getting my trigger shot (Ovidrel) injected. Does it even matter if I ovulated last night since I'm still going to get the trigger shot tonight? I mean the trigger shot is just going to make me ovulate again right? My husband and I went ahead and baby danced last night because like I said I've never had a positive ovulation on a test strip. What do y'all think?
