Can My Follicles Still Rupture After An HCG Shot On Day 14, And Are Their Sizes Optimal For Pregnancy?

Hello doctor, Since last 7months I am trying to conceive but not yet got a positive result. My age now is 27 and I have PCOS. In this cycle doctor suggested me for ovulation induction and thus I took a FSH shot and then on day 14 a HCG shot. But on day 16 I again did a folliculometry which showed the follicles are of 24*23 mm and 25.8*18.2 mm size but yet not ruptured. Is there any more chance for the follicles to be ruptured ? And if it ruptures, is the mentioned follicle size good enough for pregnancy?
