Is Pregnancy Possible After Using Postinor 1, Especially If Two Eggs Were Released During Ovulation And My Partner Is Experiencing Frequent Urination?

Hi we initially had sex on the 26th of December (protected sex) and for precaution, we also postinor 1 at that time as well. My partner had her period on the 3rd Jan after our initial sex Later on we had sex on January 14th with the majority being protected sex with a condom. For safety we also took postinor 1 on the same day after sex. My partner then got her period on the 20th Jan which is 9 days earlier, and her next period is due 17th February. Recently she has got frequent urination (13th Feb onwards). Therefore can we know if she has a chance of being pregnant? or will there be any complications? If in Jan during her ovulation if 2 eggs have been released at the same time, is it possible for my partner to be pregnant even after periods? Also is there a chance to be pregnant even after getting periods?
