37 weeks pregnant

Had my first girl at 38 weeks & I am 37 weeks this weekend. Feeling all sorts of aches and pains, but one thing that I can’t seem to figure out is this feeling I have when at the toilet🤪 it’s like I feel something about to fall out me like a clot or something but nothing ever does and I’m like a detective these days looking out for early labour signs 😂😂😂. I had a weird 2-3 days of diarrhoea and sickness now I’m left with heart burn 😂. I feel like the end of pregnancy is worst lol.
