positive opks but closed cervix??

So I've gotten about 4 positives over the past 2 1/2 days, but my cervix is high soft and closed it seems like... what do you ladies think ?? Could my honeys swimmers still get to the egg?? I'm pretty bummed because I thought everything was going perfect , my nipples have been extremely sore these three days also so I don't know what's going on. What advice do you girls have?? ☹️
