Should I tell my mom we’re trying to get pregnant? (Read description before voting please!)

For context: I’m 23, my husband is 25, we live on our own, both have good, stable, full time jobs, and are financially stable. We are emotionally and financially ready for a baby. Ive also gone to a midwife for a preconception visit and she says I’m in good shape physically to start trying.

Ok, now here’s the issue:

My mom says I’m “not healthy enough” to be pregnant and that I should “wait a few years.” She thinks I’m not healthy because:

1. I’m underweight (I’m around 105lbs, but I’ve ALWAYS been underweight that’s just my body type, and she got pregnant with me when she was 95lbs and was just fine...)

2. I don’t exercise enough (which is true, but I’ve talked to my midwife about it and intend to start daily 30 minute walks)

3. My digestion is off and I get frequent upset stomachs (also true, but she and my brother both have digestive problems too and she’s been working for decades to fix it for all of us and nothing has worked, so if I wait for this to be “fixed” it may never happen....)

Every time I talk to her about our hypothetical baby she gets SO excited and says she can’t wait to be a grandma and to help with the baby, but then always ends the conversation with “but not for a few years.” I don’t know what she thinks will change in a few years lol.

But my mom is my best friend, I tell her everything, and I HATE not being able to talk to her about this. When I’m feeling anxious about pregnancy and motherhood all I want is for her to talk to me and reassure me, because she always makes me feel so much better about everything!

So here are my options, and why all of them are bad (lol):

If I tell her now: I feel like she’ll be mad and unsupportive and think we’re being irresponsible. I think she’ll try to talk me out of it and, since I know I’m easily influenced by her, I’m afraid she’ll end up making me more anxious about it and make me doubt myself and my decision.

If I wait until I’m pregnant and then be honest and tell her it was deliberate: I feel like she’ll also think it was irresponsible, might be a little “I told you so”y if I have bad symptoms, and also will be mad at me for not being truthful and telling her before we tried.

If I wait until I’m pregnant and then lie and say it was a “happy accident”: I feel like she’ll know I’m bullshitting because she knows how badly I want a baby.

Thanks for reading lol. Please help. 😓
