I had bad on and off back pain like when AF comes, usually when i got up too fast or light movement like that. Lasting a minute max. It has subsided more now that I'm 6.5 weeks
I know that I too am experiencing some back pain. I know my doctor said that when you have experienced child birth before that your muscles are already stretched and distorted. We tend to feel things earlier than a first time mom. This would be my 5th pregnancy. I am sorry but I dont know what the beta q level should be. I know when I had concerns I searched on the net for what the normal was. It really fluctuates. As my doctor said sometimes people rely to much on the numbers. The best thing is to have an ultra sound done. Do you have one scheduled?
