Advice greatly needed

So long story short my Husband and I have been ttc to baby #2 for a year and half now and my mother has been constantly asking, today she asked and I said nothing yet I’ve even missed my period this month so I’m seeing the doctor Friday. She then proceeds to tell me maybe your going through the change im 33 I might add possible yes but very doubtful I’ve also had negative pregnancy tests. So then I said maybe we’re only meant to have the one, she then says we’ll maybe it’s for the best why bring another being into an unstable situation … my face hit the floor like WHAT ??? Unstable how ? Because my husband has been between jobs because of lay offs due to covid and yes we’ve had some financial stresses but how does that make one unstable? Our son has everything and more which she even says he does. Honestly I’m just baffled and really don’t know what to think or say I feel hurt and even somewhat a little put off. Like should we be having another baby even ? She doesn’t see our son or make an effort with him unless I go to her place or I put forth the effort, so what we bring in another baby that she’ll maybe ultimately think was a mistake because she says it’s unstable. She added that when they had my youngest brother they owned there house and my dad had a stable job and weren’t struggling with finances. I know I just kind of rambled ladies and I apologize any advice or input would be greatly appreciated. ❤️
