Bursting Belly

At 37 weeks, your belly is as big as it can get, pushing up to your rib cage on one side and pushing down to your pelvic bones on the other side. Even so, yesterday I felt Chamu has just gone through another round of growth spurt, pushing the stretchiness of my belly to its limit. Chamu was measured 3.3 kgs (or 7.3 lbs) last Thursday when we saw him on ultrasound. He looks pretty much like a full-term baby (with fat cheeks and fat limbs) and my belly looks like a full-term belly. It is hard to imagine that we both have another 4 weeks to go. I now have this constant sensation of my belly near the edge of bursting (like a water ballon near its maximum capacity). I cannot eat much without feeling the food coming out of my throat. I cannot turn in bed without feeling my bones cracking and hurting.
Chamu is running out of room in my belly so I am feeling him more often. Yesterday he was pretty naughty and kept exploring my belly with his feet, elbows and knees (even at 4am!) He has hiccups almost everyday and I go through phases of paranoia worrying to death about him not moving too much or him moving too much.
We still don't have a crib/bassinet so if he arrives early, he will need to sleep on the floor mat. I still have tons of work to do before going on maternity leave so I don't really want Chamu to come out earlier than May 15. On the other hand, my stretch marks are getting worse, belly is bursting and legs are swollen and I really cannot wait to get this over with (pretty soon I will not be able to support my body weight even with my enlarged legs).
P.S. there is not updated answer to the "C-section" question. We will continue to monitor Chamu's weight and see whether my body can really do the job of squeezing him out naturally.
