Normal bodily fluids?

Okay I was bleeding heavily which has now stopped thank god but now the last 3 nights I’m waking up like I have wet myself in the night . It’s obviously very thin discharge but it’s run all at the back so my underwear is wet at the back . I wear the big sanitary towels as well and they look like nothing on them sometimes maybe pink light blood . Is this normal ? I mean I feel like I’m like this forever !
