No morning sickness today

So I woke up which sucks cause I couldn't sleep last night. I've been so nauseated and had heartburn like crazy. But I feel ok right now. So much better. I should be happy but I'm internally freaking out. In the back of my head I'm wondering if it's because I'm not pregnant anymore or the baby isn't developing.  And that's y I feel ok. Ugh.   I wish I had a home ultrasound I'm just so worried still
