Help!! 😩

Saturday my period was due and never came! I'm never late so I was really hoping I was pregnant!! Sunday morning came and there was what I thought was my period and I had horrible cramping for the rest of that morning but nothing in the afternoon! It's weird because I get cramps in the few days leading up to my period but never anything once it has started! My period always lasts 4 days but Monday afternoon there is little blood and this morning it's like I was never bleeding at all! Could it be I only had a 2 day period or could I be pregnant???
