Ovulated or not yet?

I went to my gynecologist for a check up and we discussed our ttc journey. She said she’ll check to see if I have a matured follicle. When she did the ultrasound she could see I had a matured follicle and said it was either ruptured yesterday (12/11) or would rupture today/tomorrow (12/12 or 12/13). I took an LH test on 12/09 and then this morning (13/12) and both were negative, todays was a bit darker then the one from 12/09. Could it be that I had my peak on the 10th and just missed it?

Because of the ultrasound I’m sure that I either ovulated yesterday or will today. She said I’d be fertile yesterday/today and we bd twice yesterday and will again today ❤️
