Heavy feeling in uterus gone 5w5d- is this normal

Hi all! I found out I was pregnant at 3 weeks and 5 days and for a solid week or so I had a heavy feeling sort of stretching feeling in my uterus. The past 3 days or so I haven't felt anything. I feel less bloated and as if I could run now- back to pre bfp.

Just scared this means the baby has stopped growing or something. Also I don't have any morning sickness - but didn't with my son either. Boobs don't really hurt much. I am having the milky discharge- sorry if tmi.

Any thoughts? Sorry this is making me crazy and I have until 6/18 for my first ultrasound.
