Why does it seems more and more each day my boobs are getting heavier and heavier is that a sign my princess is on the way?!

35weeks and 2days. Belly is becoming bigger and heavier. My linea negra is getting darker and darker and I'm starting to have stretch marks as well😟... Five more weeks to go and I can hold you in my arms... 😄😆😊😙❤❤❤

My maternity pictures !! (more pics in comments)
For some reason I feel my belly more heavier today?
Wish more people on here got the progesterone shot 😩 feel like that shit fucked up my body 😐
Any heavier pregnant ladies out there?
