Raspberry Leaf Tea causing cramping??

Morgan • Mommy of a 3 year old, red headed, amazing little boy named Brooks and a 1 year old sweetheart daughter Quinn, who we call Q! Due with baby #3 in May 2018! 💕💙
Last night I had my first cup of raspberry leaf tea and I woke up with terrible cramping and just had to go diarrhea. The cramping hasn't let up, is this normal? It's not contractions, just cramping.
