I just found out I’m pregnant scared to tell for this reason..

I just found out the night after we went out. We drank and things got heated because of what our friend was saying and I got in it to defend him. And later I turned around telling him why didn’t he say anything when our friend said something I didn’t like. And things went down so fast my sister and cousin got involved. And now I’m the bad person?

Maybe I should wait to tell him when things have cool down?
