Brown/tan/pink Mucusy Discharge

Hi all!
Background:
-currently 9 weeks pregnant w/ baby #2
-MC in July of 2020
-pregnant October 2020
-full term baby girl born July 2021
So I’m looking to get some insight if this has happened to anyone before. Saturday morning, I started experiencing some brownish/tan discharge. It was only when I went to the bathroom and wiped. I did not have any cramping or pain anywhere. I also noticed that I was peeing very frequently and only minimal amounts. This continued about every other trip to the bathroom until the next day. I had an instinct that it was potentially a UTI causing me to pee so frequently & potentially causing the discharge. I bought some test strips at CVS and for sure tested positive for a UTI. I got put on pregnancy safe medication to treat it on Monday. I have only experienced the tiny bit of discharge one more time since starting the medication. I have my first ultrasound tomorrow, as I had to miss my first scheduled one due to being Covid positive. I was wondering if anyone had a similar situation or similar discharge and what the outcome was? I am completely terrified that I’m going to go to my ultrasound tomorrow and they are going to say it’s not a viable pregnancy. Any stories or experiences would be greatly appreciated. Pictures for reference.
