Is this normal?

I’m 35 weeks and 1 day. I’ve been having a ton of discharge my whole pregnancy but today I have so much i feel like I’m swimming in it 😬. It feels like my baby is so low, like I can feel his shoulders in my hips and since last night I’ve been feeling cramping in my lower back and very low in my abdomen. I just pooped last night and again today which is weird for me as I’ve been very constipated my whole pregnancy. Also my knees and hips are pinching very bad it’s hard to walk. Is this all very normal or this stage or could it be the start of early labor? I plan to labor at home as long as I can as I only live 10-15 mins from my hospital. I’m a first time mom so I don’t know what to expect 😅
