Feel like a bad mom

So today I came in to the lab to do the 3 hour glucose test & about 30 mins after I drank the juice I threw it up I told the nurse & she said that unfortunatly my test were done & I was going to have to come back. I feel like a terrible mom. I feel like I'm failing & I can't do anything right now. I feel that if I'm unhealthy then I'm harming my baby. From the 1 hour test they told me I was anemic & that's why I had to come back & now with this I feel like I'm just failing & my daughter isn't even born yet.
