I Started Taking Trazodone HCI 50 Mg On Dec. 3/16

I started taking Trazodone HCI 50 mg on Dec. 3/16 on Dec 30, I started to feel sick. I had heartburn and a churning feeling from my breasts to my abdomen. it lasted 3 days. I thought it was gone but now it is back. I am not nauseus, but my stomach and bowels feel like they are constantly churning. They are sensitive and it feels uncomfortable to cross my arms on my chest I never get dirreha but my bowels are very soft and I have been going a lot, which is unusual for me. Could the Trazodone cause this? My doctor prescribed it to help me sleep.
