Implantation bleeding?

Mauricia
I have had a normal cycle for the last 5-6 months. The last week I have been taking bathroom breaks very often and I'm consuming less fluids. I woke up three days in a row now with either swollen legs feet hands or face. I have cried 4 times in a week and over silly stuff which is very unusual for me! I have been crampy and I wake up today a week early for my cycle and it started (or so I think) it's Brown and I'm really crampy. I'm not sure what to think.... Is my cycle being irregular again or is it maybe implantation bleeding or are the symptoms just in my head wishful thinking? Help please?
