OK, I'm only 32w5d the Dr wanted a urine sample from me due to some complaints. They called told me I had a uti and they called in some medicine. Now my questions it I have no itching, burning, frequent urination, discharge( smelly or colored) BUT my underwear has been getting wet. I started wearing panty liners to see if I had any colored discharge.... no color just "liquid" clear. No smell nothing...... what is it!?!?!? Someone had asked if I thought I was leaking amniotic fluid? When my water broke with my first pregnancy it was a gush like spilt cup of water..... how would I know if I was leaking fluid??? I am now "period" like cramping in belly.
