I remember struggling with this so much back then! It gets much better once the baby is out, but for now, green veggies and plenty of water are your best friends.
Since I had hormonal issues, digestion was always slow for me. I managed it by eating small, frequent meals and drinking lukewarm water throughout the day.
Oh, constipation is the absolute worst and it makes you feel so heavy and anxious. Don't worry, it's very common, just talk to your doctor once if it gets too painful.
