I am currently 4-7 weeks pregnant, I am having the same problems, I had some spotting just when I wiped, and I went to my dr, he said he was not worried, I had it again tonight and I went to the emergency room, the dr there said he was not worried, I just had a misscarriage in december, and I am finding that I am having all the recurring simptoms of another miscarriage, lower back pain, and stomach pains, although I know that just because you have these pains and problems I still cant help but worry, if you find anything out let me know and I will keep posted on here what I find out
