Had sex with my girlfriend on her 19th day of cycle using a condom with spermicidal lube and it broke, I went to buy the morning after pill 21 hours later and she took it but on the 20th day of her cycle she had a good amount of clear discharge , my girlfriend is not very regular with her cycle and she had PCOS, we don't know of she still has it, could she be pregnant? Thank you for your help.
