Preseed Help

Keiana • Married, TTC for 3 years
So, I am using pressed during this ovulation. I don't need it because of lack of CM, just using it purely as an additional aid. My problem is - because I have a lot of CM and using the pressed, when we finish and I get up (after laying there for like 15 minutes) I go to the bathroom and wipe and I feel like I'm wiping everything out. 
I guess I want to know if I'm doing something wrong or perhaps I should be doing something different when using. If anyone who has been successful with using preseed can share any tips or suggestions I would greatly appreciate it.
