Chest and rip pains

Carly
Last few days I have woken up early hours of morning with bad pains under my boobs in like my chest/rip area. It's so painful, I feel sick, find it hard to breathe! Has anyone else had this? I am sick of telling doctors u don't feel right they just say it's all normal. (Had some swelling problems and other pains since being pregnant) 
No ine seems to care I am in pain!
