How should i feel ?

Aaliyah

I will be 15weeks tomorrow , vomiting has basically stopped I feel I have more energy but I don't feel pregnant. I'm 106pounds but no bump at all... these last couple weeks I've felt gas like bubbles or flutters but these last 2 days I havent felt anything at all, I've had a tubal pregnancy and a miscarriage last year. Am I just worrying myself ?
