When to take pregnancy test

L • Dec2019 💗 August2021 💙

Hey ladies, last night I woke up in so much, lower abdominal pain it then became a really dull pain on my left side . When I went to pee I notice some brownish pink discharge ? My opk states I ovulated on the 13th oh January And glow states that AF is this coming Monday is it too early to take a pregnancy test ? Or is AF just creeping up on me
