Lexapro and Trazodone?

Ive been prescribed Trazodone and Lexapro, due to Trazodone making me sleep better and lexapro to control my anxiety. Ive been on both for a week. I have a question, can both medications cause constipation or worsen it? Because I have really bad constipation, I cant even poop anything out. I took 2 laxatives yesturday and took one today though the box said anywhere from 12-72 hours or something. Any help would be appreciated.
I did poop out brown-ish/clear-ish water a few times but still feel constipated
