Hi All

My first time here, I need some advice/help

My period was due on the 9th October and hasn't arrived, I've been feeling really tired, nausea and my legs ache of a night in bed, also been going to the toilet alot. I had some bleeding that start on Thursday, wasn't much but needed a pad and finished last night, it didn't feel like it was my period as I didn't have the normal symptoms I do when I'm getting them. Is there a possibility that I could be pregnant?
