I feel so horribly guilty writing this but I need to get it iff my chest.

I’m just about 5 and a half weeks pregnant. Totally planned and wanted this baby. I’m so thankful and blessed that it only took us three months to get pregnant again. My daughter is almost 16 months. I have this sad feeling that she’s not going to be my only baby anymore. It’s such a strange feeling. Like it’s not just going to be the three if us anymore. I obviously love this baby and my daughter, but I feel like I’m betraying her or something. I don’t understand why I’m feeling this way. I thought I’d be happier and more excited. I know it’s early yet and it’s probably just hormones, and I’ll probably feel different after I see the baby and hear the heart beat.

Has anyone else ever felt this? Am I a bad mom? Is there something wrong with me?
