Rib pain

Sophie

I’m 16+2 and since about 12pm today I’ve been experiencing aching ribs. It feels like I’ve done a workout. It hurts when I breath and sit up for too long. Is/has anyone else experienced this and know what I can do to ease the pain? Is it something I should be worrying about? I have my midwife tomorrow so I will mention to her then! thanks! xo
