I need advice

Teleigh • My baby is due October 14th 💕🤰
So first I'm 16 years old and I'm going to be 19 weeks tomorrow. I just found out two days ago I was having a little boy. Ever since then my sister in law has been posting all kinds of stuff about me and I know it's about me because it's about pregnancy and how she's so perfect and she doesn't plan on getting pregnant anytime soon. She didn't start doing this until my brother got back from Iraq. So my mom thought it was a good idea to just make another page for the baby and not have them on there. So I did that. My brother hasn't talked to me since I told him I was pregnant and his wife told me she wanted updates but everytime I gave her updates she ignored it. So I stopped. So I guess she wanted to post all that stuff on Facebook. Like it's you lose or you lose type thing. I don't want drama nor do I need. I need advice😩
