TMI strange discharge

I had a miscarriage at 15weeks and had to complete the process at the ER to get the placenta out. I bled for almost 3weeks till it stopped about 4 days ago. I'm TTC again but I observed some very slimy egg white type of discharge with no pain at all. It comes looking blood stained to brownish at times. Any advice if this is normal particularly after sex. That was my first pregnancy and I'm kinda naive too.

Responses or similar experiences will be very much appreciated.

Thanks....
