Second trimester pain with movement

Boymom • First time mom of baby boy #1

Since I got up this morning I have had extreme pain while walking and standing in my uterus and vagina. It is a continuous pain while walking, not a sharp sporadic pain like how round ligament pain usually feels. I am thinking it is probably normal but am also scared of possible incompetent cervix. I am 19 + 5. Anyone else go through this. I was barely able to up and down the stairs today..
