I told my grandma

This weekend on Saturday night at work. I texted my grandma (the one that I live with) and told her I was pregnant. She seemed supportive over text. But my grandpa told her to be nice to me. Well Sunday went by and I left my dads and went home. Everything was ok. They didn’t anything to me about it. But this morning in the car on the way to school she asked me what my boyfriends plans and I were. I said I don’t know. We haven’t talked about it much. Then she made the comment that she wishes her friends would’ve adopted me. Cause I probably wouldn’t be pregnant right now. Then she said she would ship me off to my moms if she didn’t love me so much. But I just think my grandpa wouldn’t let her because of my 8 year old brother. What do I do? I was crying all this morning and just calmed down. I’m only 16
