Nose bleeds

 Am I the only one experiencing nose bleeds. Is this a sign for concern or leave it. I've never had them like ever. at first it started out with just dried blood in my nose a few weeks back but I thought it was from me picking it. the beginning of last week I woke up to it actually running out out my nose. them yesterday it happened like 3x in one day & throughout the night. & now it's going again. can this harm my baby ? I have been cramping and its felt like a ball in my uterine area. I have my two week appointment with my obgyn April 12th. should I wait till then or go to my primary care doctor now.
