Help please

Emely • Married 💍 Mommy to a beautiful baby boy💙 Trying to conceive baby number 2 hoping & praying for out little girl! 💕 baby dust to all of you! ☺️

So every time I have intercourse the next day I have very fertile cm. Do I have to have intercourse when I have that kind of cm or did I miss my fertile window? 😕
