Pregnancy over 40

Was single w my first 2 n have no pics of baby bumps besides in labor.Hope to inspire women as I was inspired to keep trying after 3 mc ( 2 consecutive after delivering my son at 42 ) .I workedbin a bar..got botox and accepted I had to look a certain way to pay my bills.I finally have freinds my own age after letting the fine lines n grays appear.Takes just love n guidance to parent..not as much money.Baby # 4 is very low ..and my first gender surprise baby.We had 2 first trimester mc last yr so I got back to the gym for a couple mos n took co enzyme q 10 .Finally got our sticky bean .Feeling so blessed ..wishing I did my yoga every day though..I stopped around 28 weeks due to business n exaustian but I feel a bit ashamed..I wanted to be the mom w cut arms n abs while carrying my last baby but it is what it is .Anyone start exercising third trimester ? Any positive stories helpeful... I know alot can change in 5 weeks ( imn35 weeks tmrw ) Wondering if I can strengthen my pelvic floor 🙏🧘‍♀️💜
