Chest pain

I've been in so much pain for 3 days now. I went to my normal doctor visit, hospital and still no help. I'm 5 foot and my uterus us already at its top height at 27 weeks. Thought I was having server constipation, but something is telling me it's something else. I'm have stabbing pains in the middle, under my boobs. I've taken meds for constipation, went, and still no relief. Tried meds for heartburn and nothing. kinda think gallbladder or something else. I can't move or get out of bed almost. :( anyone else experience this or no?
