Venting and first time posting in here

So me and my husband are trying for a child and me and me sister bought tickets to see the JB in concert at hershey at the end if August. I told her to hold off on the hershey park tickets because idk if I'll be preggo by then because I didnt get my period yet this month and she has the nerve to get mad at me because I'm trying for a kid and ruining her plans to go on rides cause she "had her day planned out" and doesnt wanna just travel to see a concert when this is what we've been dreaming about since we were teens. Idc about the park, just the concert and shes so mad at me. 🙄
