Please leave me alone

My brother is really excited for me to have this baby. This would be his 6th niece or nephew and I know he really loves kids but hes driving me crazy. Please tell me if it’s just my pregnancy hormones but I want him to leave me alone😭 I told him and my parents at 7 weeks. My mom/parents suffered 6 miscarriages so I wanted their support if anything were to happen. My brother(45) just so happens to live with them so he found out too. He constantly messaged me that he could not wait until July (my due date) and he shouldn’t have to wait so long. I said I’m sorry for telling you guys so early but I obviously did it for a reason (he knows nothing about the miscarriages, my health etc.) After that he was really angry with me because i wouldn’t post an announcement. He wanted to tell the whole world his little sister was pregnant which I know is exciting but again, wanting to be safe, i wanted to wait until the 1st trimester was over. He constantly messaged me that i could at least do him the favor of telling our close family members. I obviously said no. It was my body, my baby, my news to share. This upset him a lot. a little bit before that he kept asking me the gender. I had to explain to him you probably don’t find out until 15 weeks+. He said it wasn’t fair that he needed to know the gender. I said oh well I guess life isn’t fair for you then🙄 finally at the 15 week mark he kept bugging to know the gender. I told him I wanted to do a gender reveal, on zoom because of covid. He said I was selfish because I wasn’t going to tell my family. I told him I wouldn’t even know what it was so no it wasn’t selfish we would all find out together. I have my gender reveal later today and he’s constantly telling me things might go wrong. What if both colors come out, what if it rains, what if people don’t connect on time. I ignored him because obviously I do want everything to go good but he is just adding more unneeded stress. Am I over reacting or is he just being really over bearing.
