antibiotics while pregnant ( how are your babies now)

Natasha
Hey all, 
I have a 16 month old and during pregnancy I never needed antibiotics. Now I'm 17 weeks pregnant, and I've had numerous uti's and now dental problem. So I've been on a bunch of antibiotics. It scares me because of the autism risk. Just wondering if any of you have healthy babies while taking antibiotics while pregnant? 
Thanks!
