Baby worries.😳

Hi I am new on here and looking to see if any other mommies had this issue before. Im 28 weeks and 5 days. I feel like I'm already 40 weeks, I'm absolutely huge. Im having horrible lower back pains and cramps and it feels like my baby is literally between my legs. Is it normal to feel this way this early? This is my second pregnancy and it feels like it's my first. I had 0 problems with my first pregnancy it was a perfect pregnancy. And this just feels horrible!!!
