Using preseed and producing CM

Kelsey • Wife 👩‍❤️‍💋‍👨 Dog mom 🐶 TTC baby #1 w/ PCOS

So I got a positive opk today (yay!) and I’m actually producing a lot more CM then I normally do. I purchased preseed since I don’t usually produce that much. Should I still use a little preseed when I bd just in case? Couldn’t hurt right? I’m extra paranoid I don’t want to do anything to screw this month up. It’s my 3rd round of Letrozole....TTC for 1.5 years...any advice would be great thanks! 😊
