Post Partum issues

So after having my first child I bled for about a week and a half and then nothing after that until my period started again at 8 months pp. since having my second child I bled for about 8 weeks and since then have been having thick/goopy yellow discharge. I’ve talked to my doctor multiple times, I had a pelvic ultrasound at about 8 weeks pp and they didn’t see anything and seem to think it’s fine. Has anybody else experience the gross goopy discharge? I’ve never had anything like this and feel like it’s abnormal. It’s like the consistency of what my mucus plug was like. I don’t want to bother my dr again if it is just a normal part of the process but I’ve never had anything like this and feel like it’s kind of odd.
