Trigger shot help please

Hello

I took the trigger shot at 1 pm on 07/05/2024

I looked it up and it’s said I should inseminate 24-36 hours after trigger shot. 2 hours after shot I was receiving very dark lines in my LH strips.

I inseminated that Friday07/05/2024 and Sunday 07/07/2024, I’ll also be insemination today 07/08/2024

I am still showing every dark lines on my LH strips

How long will the surge last

I also am a hypoovulater mean every ovulation I release 2-3  follicles/eggs for fertilization. I was told I have two eggs this cycle that will release with the trigger shot.
