I'm pregnant with my third child and that has happened to me with all of my pregnancies. Holding your stomach does help when you sneeze.
This happens to me and when I get up from the couch too sometimes it switches sides.
Hold your stomach every time you sneeze. It helps.
Definitely round ligament pain
Irs called Round ligament pain hun. Totally normal
It's normal. Happened to me when I was around that time and still does if I get up off the couch to fast I get it and same if I sneeze very hard. I asked my doctor and she said very normal. Try getting up slower !
Try not to make quick movements remember your baby is developing and your body is changing. As far as the pain when you sneeze I'm not really sure but still consult your OBGYN
