Thoughts?

So for my first two pregnancies by this time (35 weeks) I was exhausted and had lots of pain and pressure. Gained 30-35lbs and had them early. I’m currently pregnant with my third - 35 weeks, only gained 12 lbs and feel great. Occasionally I get some pains in my vagina from his head pressing down but have any moms felt great and still delivered early/on time. I feel like I should be feeling more exhausted and ready to throw in the towel. I’m nesting like crazy tho, yesterday I cleaned the entire house top to bottom. Sanded around windows bc were painting around them. Washed floors. Scrubbed the bathroom upstairs. Etc.
