Help! Sharp jabbing pain?

So I've been experiencing cramping and back pain, so I moved my doctors appointment early, which was yesterday morning. They said no contractions, baby is fine and they would test my urine for a possible infection. But they said it mostly likely was just common pregnancy pain. 
Well all day today and yesterday, I've been experiencing discomfort and every minute or so while I'm sitting or laying, a jabbing sharp pain! It hurts where it makes me cringe. I'm just confused on what this is? I googled it and placenta detachement! Round ligament pain? Idk hoping ligament pain but not sure
Any one else experience this? I don't want to call back to the doctor since I was just there!
