Hi there ~
I have heard this to be a common problem among women who have been advised to use progesterone
capsules. It usually helps to wear a pantyliner and the capsule is absorbed in 20-30 minutes. So, do not worry of any discharge after this time. Also it helps to use your finger to insert the capsule as it is the best method for the capsule to not melt.
I hope this helps. Take care and have a lovely day !
