can u relate?

I'm 21 and just found out I'm pregnant yesterday. Me and my man(we are happy) told his parents and they are happy for us. Well it's a different story for my parents. My grandpa just passed a week ago and I feel like right now isn't the time to tell my parents the news. Also my parents are old school and wanted me to finish college travel and all of that fun stuff and me and my man are not married but we are working on it. I'm scared that my parents aren't going to be happy for us and it's really important to me for them to be supportive. New Years is in 4 days and I was planning on telling them then but I'm not sure. If anyone has been in the same situation or has any opinions/pointers I love the help😊
