Can’t seem to get over it. Overreacting?

I just would like to say I was very close to my MIL. We would text from morning to night. We told each other just about everything. I looked at her as my second mom.

Recently My husband and I decided we wanted to start TTC our second child. We are trying sooner than planned because we want our children close in age. Originally I was going to TTC in December however my MIL told me I cannot be pregnant for my SIL wedding that it would be unfair to steal her light. So we decided we would try a year early to conceive. Hubby and I wanted to keep this a secret from everyone however I wanted to tell my MIL again because I tell her everything and I wanted to share something I was excited for. Anyways my husband and I both told her and her reply was “are you sure you want to do that?” Ever since that day she would text me “I suggest you cancel your appointment to remove your IUD”

“I don’t think you guys are ready for another child. Your husband needs to focus on more important things in life.”

“You need to cancel your appointment”

“You don’t need to do that right now. Wait 4 or 5 years”

Anyways you get it now... This was happening for a month or so because my appointment was a month away when we told her. so my husband too got annoyed with her comments because it would bring my mood down and he ended up calling her the day before my appointment and they got in a big fight. Ever since then I haven’t wanted to share any information with her about anything. She would ask how I’m feeling or if I’m bleeding from it or if I’m pregnant yet etc.. I just haven’t answered her. I probably send 6 text to her throughout the day. I cut back a lot of texting and telling her things. I only answer her when she ask how my husband and daughter is... I don’t know why I’m so distant I just can’t seem to get over all the things she said to me and how disappointed I am she said those things. Am I overreacting? How can I stop being so distant?
