Jealously with second child

So I am 4months pregnant from my second marriage. I have dedicated myself to my first child who is 11yr old and continue to love her and care for her the same way even after the baby is born. I raised my 11yr old on my Own. She seemed to be ok with having a sibling, my husband and I treat her like a queen because I’ve always on my own when I was single would also spoil her. I think she is getting a bit jealous of the new baby yesterday she told me she regrets asking for one. It hurt my feelings but I completely get her as she’s never really had her dad around and It was mostly just mommy and her. I don’t want to hurt my kids feelings, I will love my 2 kids the same. Anyone else had this experience? She’s such an amazing kid I love her so so much, and I will love both equally.
