Fleabane (Erigeron sp.)?

I’m not sure what this is. It grew at home last year but hasn’t appeared this year. The flowers look like a fleabane but the leaves are unlike most fleabanes. I’d appreciate any help to identify it.

Flower buds just starting to develop.

Flower buds just a little further along; petals are white at this poin.

And further still. The buds have a pink tinge.
