How unhealthy is being slightly underweight as a woman if you eat a nutritious diet?

I'm a 5'5 29F. My weight as an adult has generally been between 120-140. I recently lost some weight unintentionally due to various factors and went down to about 95. The factors causing me to lose weight have resolved and I am slowly gaining weight again, currently about 100-105

I know a few pounds overweight isn't a huge deal health-wise. How negative would it be for me to stay a few pounds underweight, about where I am now or just slightly more? I know much lower is dangerous, and I definitely do not plan to go back under 100 pounds (besides health reasons, I hated how I looked that low anyway). I don't have any history of anorexia/bulimia/etc

I eat a pretty healthy diet - mostly whole/minimally processed foods, largely but not entirely vegetarian (my LDL was bordering high at my last bloodwork so I've been trying to cut down on saturated fats lately), with plenty of fiber, fermented foods, etc and I take some vitamins. I usually have a small sweet treat daily but otherwise I very rarely eat junk food. So I do try to make sure I'm doing well in terms of vitamins/minerals
