Short answer? Yes. Long answer? Let's take a closer look at what could be aggravating the problem. Aside from period interference, constipation can also be caused by lack of fiber in your diet. Being a nutrition fanatic, I always recommend that people get their fiber from natural sources, like fruits, veggies, and whole grains. Try upping your fruit, veggie, and whole grain consumption the few days before and during your period to see if it helps. It's also important to drink plenty of water to keep everything moving. If those things don't help, and if the problem starts interfering with your life, it might be time to make an appointment with your healthcare professional. I have to say, I usually have the opposite problem when I'm on my period! So I understand how your period can interfere with your poop schedule in an annoying way. But making sure your nutrition is on point can really alleviate the problem!
