I would call your doctor you could be having a slow leak. Which happened to me with my first daughter. Especially if it soaked threw.
Well i have an appt at 2 so i guess we will see thank you :)
You can expect discharge to increase as you get farther along. Its called Leukorrhea and is due to increased blood flow and estrogen.As long as there is no blood you're OK...but if you have any concerns always ask the doc to be safe ;-)
