Last night when i was sitting in bed all of a sudden it was really hard for me to breathe, i felt a lot of pressure in my chest and it was really hard to get up or roll over. I tryed walking, laying on both sides, and i was still having a hard time breathing. I started to panic. Today I can breathe just fine but it feels like my right rib is being lifted up, or like the baby or something is stuck under it. Anyone else experience this? Is the baby that far up at 28 weeks? What can help?? THanks
