Shoulder dystocia

.

Question about it ... my first I pushed for 3 hours - she was sunny side up so it just took longer for her to get through. My second was 15 min of pushing but halfway through her shoulder got stuck(she was 7lb 8oz) The nurse pushed above my pelvis and easily dislodged her shoulder. I didn’t even think to ask about it this time around. I’m due Monday, but no one said it to me either through this whole pregnancy. Only reason I think of it is because even though the growth scans have shown that he is on the smaller side I feel an elbow or shoulder digging into the right side of my pelvis occasionally. I’m nervous about it happening again. Has anyone had issues the second/third time around?
