Help!!!

I posted yesterday about having diarrhea at 37 weeks +1. It only happened once when I used the bathroom for the first time that morning. The rest of the day I didn’t feel any of the normal cramps that come with Diarrhea so I just put it down to being pregnant. However today I’ve woke up and went for my morning pee and I’ve had Diarrhea again. I’ve been getting lightning crotch and my discharge is coming in abundance. I’m only 37weeks2days pregnant. Is it really impending labour? Or just usual pregnancy 🙄. Ps I haven’t had Diarrhea throughout my pregnancy at all so this is a bit new for me and I really want my baby to make it to 40 weeks to be as strong as possible!
