Ok, so I'll be 35 weeks on Saturday and the closer I get to the end the MORE pain I'm in 😔... My groin area hurts I be wanting sex but I can't with the pain 😖... It takes me bout a minute or two to get up from sitting down or laying down and let's not talk bout the back pain I get ... This is my second pregnancy but this baby is so much bigger then my oldest. My oldest daughter was only 3 pounds at birth but this little girl is weighing at 4lb at last ultrasound ... Any reason as to why I'm in so much pain ???
