Brown discharge HELP !

I have been having brown discharge since I was 6 weeks I’m 9 weeks now and still having the same discharge. It’s like clots you get when you on your period, they can be long and short. Instead of dark red it’s dark brown. Sometimes it’s like brownish brown and clear mixed together. They are slimy, and it’s not just 1 coming out it’s a lot coming out, every time I wipe I feel so dirty because the wetness it causes it’s like dirty brown. I clean with water every time I use the bathroom so I know I’m not dirty like that, this started happening when I hit 6 weeks and before this started I bled like bright red and it was a flow instead of spotting blood and it went on for two hours but than stopped. Couple days after that, this discharge started. I have no idea why I’m having this because my first pregnancy I never had this. Is it because I got pregnant at 5 months postpartum? This discharge is annoying, I be scared on having sex with my husband because I don’t want him to see this nasty discharge and think I didn’t clean myself because he doesn’t know about me having this discharge. Help !
