I have been bleeding for almost a month now I started if the 10th if may and stopped on the 15th of may then started again on the 18th of may and still going I had a baby 7 months ago and do have irregular periods but is this normal?

How much bleeding are we talking about? A pad a day? A pad an hour? This is really something I think you're going to need to talk to your doctor about there might be a hormonal issue at play here.
