Pregnancy Scared

I had my November period from the 22-26th the following day on the 27th me and my boyfriend had protected sex but then the condom broke. šŸ˜”šŸ˜±

Immediately as we noticed the different feel he put on another condomn and we continued he did not cum in the condomn because he pulled out with the condomn in tact and we proceeded to oral sex where he came.

I had my period on December 21-24 and somewhat spotting on Dec25th and now I am very nauseous, is there a chance I could be pregnant.
