Confused

So I went to the ER today cause I was puking and had diarrhea, they said it was a stomach flu going around. They did a CT scan said my small intestine is swollen( I have crohns). Also I’ve been taking my bc religiously. Idk if I’m pmsing or not but I’ve been very anxious. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says my period is due in days . What are the chances that I’m pregnant
