Domain changed, will it affect my affect ranking

So i started a website around October, had over 70 products, they was ranking on google, most pages were ranking on position 3 and I was getting good amount of traffic, I changed my domain only 7 days ago and I noticed all my products were no where to be seen whenever I search for the keyword and product name I was ranking for, but my website is only about 3 months, will everything go back to normal or is it bad?
