I’m pregnant but my mom has the symptoms

So I am pregnant with my 3rd baby. And I am tired of people asking if we planned for this baby. This baby was a surprise and destined to be here. But no I didn’t plan for this baby. Actually the timing is bad. We were being careful, I have used to calendar to get pregnant 2 times and to avoid pregnancy for years. Nothing is 100% effective. But anyways. My mom is being so rude. She keeps telling me that good luck to me that I should have been careful and on the pill. Or maybe gotten surgery to avoid pregnancy. Now. We don’t live together. I don’t depend on her financially. BUT she does babysit my kids while I work. And I am bitting my toung 👅. I don’t have another babysitter and I will have to quit my job after I give birth to my 3rd baby. But I don’t know how I can do another 7months of this. Like this baby is already in the way, leave me alone. I will handle it. It bothers me. She also claims to get really emotional during my pregnancy so I have to be extra nice to her. But she won’t accommodate to me, my pregnancy hormones don’t matter. She gets the moodiness and cravings 😒. I’m so annoyed. I think she is prenapausal (idk how to spell) but I don’t think it’s fair to me idk. Am I being too emotional?
