IM WORRIED.... I just drank a tea

Ga
So my throat hurts so bad, so I decided to make hot a chamomile tea ... I finished it and my throat feels a lot better but I just read that some teas are bad during pregnancy, specially during the first trimester :,( I feel really worried now... Now what?
This is what I read: 
chamomile has such powerful anti-inflammatory properties that regular consumption may result in a serious fetal heart problem, premature constriction of the fetal ductus arteriosus, which allows the fetus to "breathe" in the womb.
