Glow ladies so need opinions

So when I had my daughter July 13 2019 I sent my little sister pictures thinking she would wanna see her niece . Well time cone after she was born and my sister seen the message then got mad and said I sent it to her to make her jealous cause she is 37 weeks pregnant and trying to do what she can to have her baby. I felt pissed cause she didn't even ci gratukate me like anyone normal person with a right kind would've. Well a few days ago I took a pregnancy test and found out I was pregnant again not planned but I am happy and excited and she got pissed of just today after I made my announcement causing a scene then posting that she is expecting her second baby and not to be mean she don't need another she don't have money nor her own place they living off her boyfriend's mom and I still congratulated her after she had told me I can't see a midwife till I am 8 wekks like I have 5 kids about to be 6 it is prenatal appointment then they schedule a ultrasound for 8 weeks. My problem is she acts like everything is competition and it pisses me off so I had blocked her after telling her how it is. Like you hate or congratulate and she obviously hated. She wants attention and I didn't get pregnant to get attention. Maybe I'm taking it personal but my problem is I've congratulated her after she had her son two weeks after I had my daughter and she got jealous cause I had a girl as well like is it best to keep her blocked on social media I don't need her craziness.
