Just entered my 27th week and wow it's a huge difference. Up until now I've felt ok, now the acid reflux is TERRIBLE even with Zantac, back hurts, round ligament pain, cramps, waking up in middle of night, shortness of breath, close to getting gestational diabetes, just can't get comfortable. What week did symptoms really kick in for you? This is my first and I was so naive to think up until now that this wasn't so bad. Not the baby I love the baby but just the pains of pregnancy.
