just found out about our 5th child

so my period was suppose to start last Wednesday it's 3 days late every month so I didn't panic until Saturday was 4 days so I took a test yesterday hoping my stress just had me off . I took the test and it was positive I didn't believe so I went and bought two more . both positive . I was honestly so in shock I cried. I was suppose to get my tubes tied may 24th🤦🤦🤦 my husband is so far way more okay with it than I was expecting to be honest . but our family is always saying stuff about I need to get fixed and 4 is enough . honestly I don't care I love being a mom . we love our children . we have been together 9 years married for 1. so there's step or half children . but I don't know how to announce it or if I even want to . but I know I can't hide it forever I just don't want all the rude comments . mostly from our mothers 🙄🙄 . what would you do .?
