Its normal.My first was a girl,im having a boy now 19w and 3 days today and my belly is much bigger than my first pregnancy which is normal.I have hip pain at night and lower back pain and have to find ways to sleep and get comfortable,standing for to long is a pain,its very normal.I've had Medicaid for my first pregnancy as well as this one and it covers all my docters visits,delivery,and three weeks postpartum visits.Try applying at Department of Children and Families.I wasnt able to afford other insurance at the time and Medicaid has helped alot.It will also cover your babys docter visits after birth.
I'm the same, never felt anything with my first. But this time I get all different pains. I'd say it's normal :) if you're really worried and stuff it doesn't hurt to go to the hospital or see the Dr if you can :)
