Constipation.. Help?

Brittanie • Ariel Diana Nichole was born 9/7/16😊 Pregnant with my 2nd 💕
7 weeks today and for the past 2 days I've been so constipated that it actually hurts. Has anyone else had this issue yet? And is there anything I could eat or drink, or even a medicine that wouldn't harm the baby that I could take?
