Stomach hurts almost all day

Hello, I've been having a lot of stomach pain since before I found out I was pregnant. Like I have some pains and cramps like I constantly need to go to the restroom.. the pain even wakes me up at night. I'm waiting for my first appointment with my OB but In the meantime would anyone know if it's safe to drink chamomile tea to soothe the stomach pain? I don't remember these pains my first pregnancy.
