Feeling disheartened

We just moved about 2 weeks ago. I saw my new doctor last week. Just got a call telling me I have a UTI and BV. This pregnancy has been hard. I have a toddler and I am unable to rest as much as I did my first pregnancy. A week before I found out I was pregnant I found out I have thyroid issues and will have to take medicine the rest of my life. I had some spotting right before we moved. That turned out to be a cervical polyp. I've had really bad nausea and even ended up in the ER due to throwing up even water. I just want my baby to be safe and healthy. I can't help but feel like I am doing something wrong. I'm worried 😩. I'm just happy I'm able to feel my little one move a couple times a day.
