Ladies,, could use some advice and kind words

I’m seriously obsessing over everything during this pregnancy. I’m 19 weeks and 4 days, i have some light cramping, sometimes tugging and pulling feelings. Some looser stools (not diharrea) feeling pretty energized mostly, I do take iron. I don’t sleep well, but I don’t feel movement and it’s bothering me. Her heart beat was in the 150s about a week ago and I have a fine pregnancy but still have this awful fear. I’m pretty big and feel like I should feel her, she is not my first baby. Any advice? :/ I feel soo lame.
