Am I being overly sensitive?

So I’m almost 8 weeks pregnant and can’t tell if it’s hormones and I’m being way too sensitive or not. So my boyfriend was on the phone with his mom she was on speaker and didn’t know I was sitting right here and was telling him about some family dinner, then she said he could invite me if he wanted but you don’t have to. The but don’t have to makes me just feel like unwanted. Like I’m not a thirteen year old pal you tell your kid they can have there with them wtf. I dunno it’s bothering me. They don’t know I’m pregnant yet either and now I’m like hmm wonder if that will change.
