Signs of labour ?

I lost some of my brown, blood stained mucus plug on Saturday lunchtime. Yesterday, I felt relatively ok, just intense Braxton Hicks in the evening.

Then throughout the night I kept waking (perhaps 3/4 times) having basically vomited a load of acid into my mouth- it was awful. This morning I woke up and went for a wee, which very quickly turned into a poop, not diarrhoea but a little looser than usual.

I’m only worried as I’m only 35 weeks today 🥴 are these signs that’s something may be happening??
