Possibly pregnant

Nichole • Expecting our first January 16, 2019💙Silas
So my fiancé and I had a little incident with a broken condom about two weeks ago. Since then, I have had boobs that can't be touched, I'm sick to my stomach all the time, I have constant heartburn, and I think I could possibly be pregnant. My period was supposed to start yesterday and it hasn't yet. Thoughts? I'm kind of freaking out a little.
