Not a big quarrel with husband, raised voice, a little nervous moment. could it harm my baby i am 13weeks pregnant?

Unlikely: Very unlikely that you have hurt your unborn child.

Should be OK: There is no such thing as a match-made-in-heaven, thus all couples get into some disagreement at times and different emotions go along with that. I would not worry much about the incidence. Baby should be fine. Continue your healthy lifestyle--balanced diet, healthy and exercises take your prenatals and follow-up with doc regularly. Congrats on your pregnancy and good luck.
