stupid constipation

I'm currently 7w2d & I was worried because I haven't been cramping much the past week or so & I was having some cramps. Get home from work worried (I had a MMC with my first pregnancy at 9w, baby was only 5w3d) so I'm all anxious. Only to realize that I finally have to poop for the first time in 3 days, that's why I'm crampy. Soon as I'm done cramps are gone. Like yay but ugh. Lol Am I alone in this? Haha
