I'm currently 5 weeks preggo, and I've already had a miscarriage last year at 7 weeks. I had cramping and spotting last time, so you can imagine I'm super nervous this time. The weird thing is, I only cramp and experience light spotting at night, after I've gone all day at work (desk job) with neither symptom. I had a doctor visit earlier in the week and my 5 week ultrasound looked great, but the symptoms at night are really worrying me. Not only that, my right rib began to bother me today. Like a little sharp pain under there. Should I be worried?
