Weird Ovulation question

Devan • Mom of a smart and active 6 year old...I`m a nursing student
TMI: So I'm on my fertile week according to GLOW...and I have been super wet starting mid last week....my bf and I had sex the last days of my period and have been having sex since. Well today I went from really wet to unbelievably dry! Is that normal on the 4th day of the fertile week?
