Losing my mind 😡

My daughter goes to her fathers house every weekend and has been bringing home a different cold every week 😒 First she had a common cold the following week strep throat and this week she has been diagnosed with the flu. My ex knows I am pregnant but continues to send her home without taking her to Doctor; the past 3 Monday's I have to take her and spend the week getting her healthy. I am tired and I am so worried about getting sick 😭 luckily I have seen two ultrasounds and the baby had a strong heart beat both times. We get to here the heart beat again this week but till then I'm so worried about getting the flu.... Needed to vent! Thanks
