Feel like I’ve hit a wall

So I’m 35+5 and with just 30 days to go I feel like I’ve hit a brick wall. My last baby shower was Saturday and ever since then I’ve been nauseated non-stop, lots and LOTS of indigestion, burping and gassy 🤭 I was sleeping so well for the first time in WEEKS and even that has stopped now! My mom says it’s my body gearing up and that I will likely feel this way until little guy makes his arrival. Please someone commiserate with me or tell me this is all part of the process! I now understand why women are like GET THIS KID OUT OF ME by the end of pregnancy lol 😂
