Morning after pill

Hi everyone, first i would just want to say that I personally don't have much experience regarding sex and my boyfriend is from a very conservative country and unfortunately was not taught much about women so we are both on a learning curve. I am looking for explanation or advice...

Anyway we had our first time together on a Sunday but the condom broke half a second before he came. He pulled out quickly but i was still fairly panicked so we both went to get a morning after pill. I took it but few hours later we had another intercourse. Just to clarify it is fully my fault and not my boyfriend, but i have issue starting with the condom right away because my body is more on the dry side. We had no access to lubricant so I did ask him to just start without condom for a few seconds and then he put it on.

Is the chance of pregnancy really high if this was done a few hours after taking the morning pill? I know it was very stupid of me so no need to say it again i won't do that again ahah
