Ugh 😩 upset stomach everyday

For 4 days straight, I get a really upset stomach and end up with the 💩. My stomach hurts so bad every day. I’m 33 weeks and 3cm and 80% effaced. I didn’t have this with my other pregnancy, I was always constipated. This isn’t normal for me as, I normally have to use stool softeners or suppositories to help me go. Ugh 😩. This on top of irregular contractions since last week, Hardly sleeping, I’m feeling like I’m going nuts. Honestly hoping labor here soon. My last was born at 34weeks and my first at 36 weeks. But I know baby needs to stay a bit longer 😭😭
