Weird things started happening at 33 weeks — is this normal?

Anyone else have weird things start to

Happen at 33 weeks? Change in bm frequentcey, texture? Nausea, mild period cramps off and on. Constant Braxton hicks whenever I stand up or sit, losing bits of mucus plug, strong urge to pee but nothing comes out or a little bit at a time, sometimes hurts to walk feels like she is going to fall out. Don't know if these are normal things or if I should be concerned. It all started this week at 33 weeks.
