What Causes A White Discharge Post Inserting A Vaginal Insertion Capsule?

hi. my ML is 6yrs. On 14th mar 2011(11th day) IUI was done to me and on that day itself my egg ruptured. From 18th mar 2011(15th day) i have been asked to use SUSTEN VT 200 daily 3 times. My doc told me that it is a vaginal insertion capsule. but the problem is after inserting it, for 1 to 2 hrs its ok. but when i start doing my household chores i observe a white discharge may be the tablet is melting. Are there any side effects to it. Is there any problem with that type of discharge. Can normal intercourse can be done. If yes, then before insering the tablet or after inserting the tablet can i have the intercourse?not to worry about this discharge
