Zoloft anf pregnancy

Found out I'm pregnant today! I'm only 4 weeks, but I'm on .50 mg of zoloft for anxiety. Please give me feedback about experiences with zoloft. Since finding out I'm pregnant AGAIN (#4) my anxiety is in high gear and I'm not sure I can handle this pregnancy without it. Please share your experiences! I'm posting anonymously because I don't want hateful comments. (Which hopefully their won't be any)
