Oh my god these cramps literally woke me out of my sleep. I usually get back cramps as well and those have started. also I'm getting this sharp shooting pains mainly on my left side but is happening on the right as well. is this normal at 15 weeks? I have an appt at 3:30 today should I call my midwife before that?
