2nd time mommas, how much longer would you guess I have?

My first baby was breech and so I didn’t go into labor at all (planned c-section). This baby is head down and everything feels totally different. I’m 36 weeks and I feel so much pelvic pressure, like baby is just too crowded down there. I’m experiencing hemorrhoids for the first time ever, which I figure has to do with this baby being lower than my 1st ever could be and all of the pressure that causes on blood vessels and such. And today I began to get just horribly uncomfortable and crampy. I feel a lot of lower cramping, which is new and more painful than the Braxton Hicks ones I’ve been feeling up til this point. And lastly the pressure is so intense that today it hurt while walking, as though the bounce of my steps was drawing him lower and lower into my pelvis.

Does this last the whole last month? Or...does this mean he could come sooner? I’d love for him to stay in as long as he needs to, but today was so uncomfortable that I hope I don’t feel this way for a month.
