blessed, nothing can be done abt backache lo. 2 weeks back i was also on 3 days MC for heartburn. My heartburn attacks every night. And yes, feels so zombie. I always tell my hubby im so sleepy and yet cant sleep. Now when i walk i need to hold my tummy slightly, i think coz bb is pressing downwards, i cant walk properly.Lying in bed certainly dont work for me, coz got heartburn ma. So lie also cannot, walk also cannot. Recently heartburn is getting v bad. Sometimes when i bend down to take something also can feel it coming. Luckily, so far my feet got no water rentention but have been getting my nightly cramps. So with heartburn, backaches, cramps and the HEAT, it's almost impossible to sleep. I cant wait for my bb to come out. But of coz, i doubt can sleep much when she's out? Now in my 30th week also, hopefully she can control her weight! haha
