Severe bloating

Stevi

I’m just now beginning my 2nd trimester and I am struggling badly with extreme bloating. I take miralax because it works the best for me every day or every other day, depending on whether or not I have stool softener. I can’t drink as much water as I did before and I eat a lot of carbs due to nausea. By the second or third day of not going to the bathroom, I feel awful. I feel like I’m carrying around 10 pounds of toxic waste and it makes me feel ill. I also take fiber. Why is this? I am struggling so bad. After I finally go to the bathroom I always feel so much better.
