Constipation in 1st trimester

Sabrina • My first love, my son, is 4 years old and now I am pregnant with a baby girl due 12/23/15!!!
I am 9w 2d and I am so constipated:( I hadn't gone for about 4-5 days then had extremely painful horrible cramping diarrhea and now 5 days later with nothing since then. What have any of you done to relieve constipation without causing diarrhea?
