29 weeks tomorrow

So I'm officially 29 weeks tomorrow ,it's been a long road glad to hit my 10 week countdown next Friday. Anyways . Since I was about 27.5 weeks I wake up to horrible cramps like HORRIBLE. Idk why I drink all water, I walk every night, at least try to , I sleep pretty much all day most days , I swell a lot at this point, hands wrists, face and feet. It's pretty crazy . Just wondering if these horrible cramps are normal . Have a lot of discharge but from my understanding that's pretty normal .
