Help pleaseeee

Me and my fiancé had protected sex on January 6th which was during my ovulation. But later after we finished I found a piece of the condom in me!!!! So it was pretty clear that it ripped. I didn’t take plan b or anything. But lately I’ve been experiencing cramping, nausea, fatigue, very bad mood swings, etc. I took a test today and it was negative. My expected period is the 20th of January. Someone help?
