I'm 5.1 weeks pregnant as of today. For the past three weeks, I have been having a dull pain in the lumbar area of my back. I also feel bloated, maybe, or slight pressure in my lower abdomen. (It reminds me of the feeling you get when you are about to begin your cycle- minus the cramping- it's not painful at all). It's like a feeling of heaviness or fluid retention. I am a nurse, and I am on my feet all night, and of course, I do not get enough sleep. Is this a sign of a possible misscarriage or is lower backache and bloating a normal symptom? I have had no bleeding. Im very worried. I'm getting mixed messages from coworkers and friends, and my MD appt isn't until May 18!! Please help!! :)
