Should I wait until my Dr app or should we call for a sooner day?? I've been spotting a little bit (I noticed when I'd wipe) and I have been feeling nauseous for days and I have a sore throat in the mornings only. Also i have had so much pressue lately and pain that feels like stinging with the pressure

My next app is on the 18th
