What are fourth pregnancy differences from previous pregnancies?

Every pregnancy is different. I am pregnant with my fifth child and it is totally different. What I notice is my tummy is expanding earlier than the first two and I am more susceptible to pulling my abdomen muscles. I am glad to tell you that I can feel the baby moving earlier than other pregnancies. Each pregnancy causes your muscles to relax just a bit more and with this pregnancy and the one before I was able to feel the baby move earlier than with the others.
