Yeah it’s super normal for it to start and stop. However, it might be your first period. Some people will get a big gap before it and others it’ll come quickly. With my first I got my first period two weeks after I’d stopped bleeding from the section x
I had the same and triage said it was normal - any concerns up to 28 days post birth you can ring your triage unit for advice before going to gp. They said to me it’s normal to stop and start for a bit and only a concern if it soaks a pad within 2 hrs, you pass a clot bigger than a 50p piece or any bad smells etc
It might be your period coming back? Best to check with your health officer/GP
