Scared

Mary
Back in august my husband and I lost a baby at 20 weeks. The day after Thanksgiving we discovered we were already pregnant again. 
I am now 17 weeks pregnant and nervous constantly. I was recently in the hospital for a horrible kidney infection but upon release became violently ill from the antibiotic.
I've already had two other children, so I know I've felt this baby move, and since I have been home, the vomiting occurred and I haven't felt the baby move since I had the reaction. 
I'm so scared to lose another baby.
