Any advice???

Hey everyone last night I was at breaking point and over dosed on tramadol I went to hospital and got checked after my mum found out I spent hours waiting on test results to come back and was so exhausted that the nurse told me I could go home and she would ring me when they came back I haven’t heard anything back yet apart from a phone call from the mental health nurse. Last night a while after I took the tablets I started to bleed it is quite heavy but it is brown I did not tell anyone about this as i thought it was irrelevant I’m not sure if I could’ve been pregnant or this is due to taking the tablets would anyone know what this could mean or have any advice without judging me thanks x
