This is my first pregnancy. I'm almost at 7 weeks. My first prenatal exam isnt until the 8 week mark. ugh. I hate the waiting. I'm getting nervous because this weekend I did a lot of walking and sight seeing while on vacation. I probably did about 16,000 steps each day. now I'm spotting. it's light and pink and really only happens when I have a bm. should I be worried about a miscarriage or is this normal? have I put too much stress on my body from all the walking? I'm not having any other symptom like cramping but my morning sickness last night was the worst it's been the entire pregnancy.
