First time mom

Hi, I would like to know what should I do with that.. Im 29 weeks and today I felt like my baby was less moving than usual but she is actually moving but not as much as im used to, im worried, I used my doppler to find her heartbeat and she had one. Yesterday I was panicking because of the shower and because im not ready at home to get baby, I just have a crib pieces, I miss tools to get it done. I was cleaning and feeling soreness on the sides on my belly and today I feel like my belly gets tighter much often it gets hard for less than a minute.. I wanna go to the hospital but I don't know what to do right now... boyfriend told me to relax and wait until tomorrow to see if it goes back to normal.. what should I do?
