Help how does sperm get into cervix if its closed???

Mandy
Was wondering if you have sex during your fertile window ...and your cervix is closed then how does the sperm get there? Does it stay in your vagina til ovulation??? Sorry I can't seem to get anyone to answer this for me ..... I ask because me and hubby did it everyday til two days ago he got called in for a job ...and I thought well maybe there is still a chance ...did a cervix check and it was completely closed and thought well how do they get in? ...am I out??? My cervix today is very open now but ...maybe its to late for me ;( maybe I am out this month ...any help?
