Used boric acid last day of fertile window

I had sex everyday of fertile window and the last day I had sex around 10:30pm and put a boric acid in around 2 something Am before laying down(felt like ph was getting knocked off). Will it prevent any chances of me still getting pregnant. I read somewhere it takes sperm up to 45mins to get through the cervix, and it was longer than 45mins before i inserted a capsule, I’m nervous I messed my chances up.
