My pregnancy is in 19th weeks right now and after being on my feet for small periods of time I start to get a back ache in my lower back and I can’t understand the reason behind this. So I want to ask this from you guys, how can this possible when the baby is only 11 cm long and only weighs around 6 ounces! If I am already getting aches in my back, what could be the third trimester going to be when baby actually weighs for several POUNDS!
