Hello, I am about 4 weeks and 3 days pregnant. I have been having some lower left back pain for a few days. The pain is mild and feels almost like a tugging sensation. I feel like I am very constipated and bloated also. I also had very few drops of light brown spotting on Saturday and then a little yesterday morning. I called my OBGYN and talked with the nurse and she said that the spotting was normal, but at the time I was not having the back pain so I did not mention it. Like I said it is very mild, but it is noticeable. I guess what I am worried about is an ectopic pregnancy. Does this sound like what it could be? I don't want to over react and call my doctor again. Any advice will help. Thank.
