This is my first child so please bare with me. I'm 36 weeks along and the past couple of weeks I've been experiencing more frequent and painful BH contractions. For the past couple of hours though I've been getting sharp shooting pains in my lower abdomen that sometimes come with contractions and sometimes not. I have a lower back ache as well. Should I be concerned that this is labor? I haven't noticed my waters leaking nor have I lost my mucus plug. I haven't been able to see my doctor in 3 weeks so I don't know if I'm dialated or not. Do any of you know what this could be?
