Having lots of discharge today. Went through two pairs of underwear already since 7am. It is now 3:30pm. Its clear and doesn't have a smell to it at all other than being faintly tinny like blood but there's no blood at all or even a tinge to the color, its perfectly clear. Do you think its just extra discharge or should i get it checked out? Im 29 weeks and have had mild cramping today as well. What should i do other than slap a pad on? Im getting a little worried.
