So I had my ob appt at 3 today, I was feeling okay there, then me and my boyfriend got something to eat and headed home. While we were eating the lower right side of my back started to bother me. On the way home it got worse and getting out of the car I could barely stand up. I'm laying down now and it feels better but I don't want to know what it's goina feel like when I get up. What could this be from, baby dropping maybe?
