Hi, on Saturday I got my period which has always

Patient: Hi, on Saturday I got my period which has always been heavy for 3-5 days and never anything less. This month it lasted 1 day and wasn’t too heavy then I had some brown patches of blood though out that night. On Monday I got a extreme sharp stabbing pain in my left side when was uncomfortable for a hour or so, I’ve since had a pulling pain there and what feels like electric shocks. The left side of my back is also very sore and I’m finding it hard to get comfortable. Just looking for some advice please. Could this be a sign of pregnancy?
