Period was supposed to come today

Lea

I’m supposed to be getting my period today. I have all my usual symptoms which are mild cramps, dehydration, grumpiness, and cravings for chocolate but there’s no blood yet.The last time I had sex was the day after my previous period. My ex came on my stomach. Is it possible that I’m pregnant? I haven’t had any nausea or spotting or any breast swelling.
