Mucus sack looking stuff in discharge!!!

Currently 5w6d and I am doing vaginal progesterone infections... I've started trying to clean myself out at night n the shower because it literally gets nasty with all that cream built up... Well I've had some brown bleeding since before i had a positive test (so sorry for the TMI and disgusting details) but it basically looks like mud coming out of my poor va-jayjay. Tonight I had some mucus sack looking stuff in the discharge!
