Backache!

I'm not sure if this is from overworking myself...or from pregnancy but my back is VERY sore and I've never felt this ever in my life! I will supposedly be 6 1/2 weeks by my first OBGYN appt on September 21st...according to nurse when I made my appointment bit not really matching with this app!! I guess...I have to wait until my appointment which these days are dragging byyyyy....trying to stay stress free and calm in the mean time.Anyone else have an extremely physical job? My boss told me try not to stress and to not pick up heavy things......I work in the hotel industry btw.We will see what the midwife says September 21st! Pray for Us!!!!
