Pray that Tobin stays safe ... My infection is lingering

So thankful that tomorrow we are at 33 weeks and that my blood pressure is back in the normal healthy range, but I would like some prayers of protection for Tobin. My urinary infection is lingering, it is still minor, and still typically wouldn't be treated. Over two weeks ago my numbers detected 60,000 units of E. coli, for a "normal" person they wouldn't treat unless the number was over 100,000. Given my history with Koen, treatment is necessary for me. At the time of Koen's death my numbers were only 60,000 - also very minor and I had no symptoms, no fever, no indication. I have been on antibiotics for over two weeks, yet my latest urine sample shows a level of 40,000. That number should be zero. It's "okay", but concerning. I am now on a new round of antibiotics, and my doctor literally said his fingers were crossed in hopes of this new drug working. My sample could be impacted by outside contaminates, but the only way to know that is to take a sample via catheter and a catheter can cause a UTI! So we don't know, we can only trust and pray. Our doctor says that because Tobin is farther along than Koen, he is more resilient, and he believes if an infection would start in my uterus that I would go into labor before Tobin's life would be threatened. We don't know anything for certain, I am a unique case, that seems to get more challenging by the week. I am fine with having the infection and taking the drugs needed, what I want is Tobin to stay safe. Please pray for protection for our Big T. Given what we went through last year, this makes my mama heart nervous.
