Help! Can somebody please answer this question? Cant seem to find the answer anywhere!!

You are suppose to have sex during your fertile window leading up to ovulation ...but if your cervix is closed how do they get there ??? Do they live in your vagina til ovulation??... .I'm wondering this cause I had sex 2 days before ovulation and hubby had to work and no time for sex we did it everyday til 2 days before ovulation.. But I realized my cervix is closed so where are they gonna go?? I've asked a bunch of TTC forums but still nobody has been able to help me out ... Can anyone be so kind to answer this for me?
