Late period....!

Raquel

I never have been irregular have but this month my period decided to skip... I'm married and I have one kid (3yrs old) and we are hoping for more babies 😍 My period has been late for 18 days now and ever since then I'm having this mucus discharge for no reason... I have taken a pregnancy test but they have come negative ☹️☹️☹️ anybody know what the mucus discharge could mean???
