I'm 35 weeks and have pain just under my right rib, it feels as if there should be a bruise there-but there isn't. I have had a headache for the last couple of days and have constant heartburn even though I'm on 2x ranitidine daily. Been waking up during the night either being sick or feeling very nauseous but again this I think is stomach acid. Basically I just don't feel well. Anyone else had anything similar?
