Could I be pregnant or what could be happening?

Hi ladies! I’m new here. Been TTC since Nov. 14th. Which is the day I got my Mirena removed. I started what I assume was a period on the 16th that seemed normal. ever since I got off my period my boobs have been EXTREMELY sore! Like barely touch and it hurts. Per another app today is my ovulation day (I just got Glow today) but I had almost like a slimy/bloody discharge earlier and idk what is going on... I took and test Friday knowing it was too early but couldn’t resist. Any one have any thing similar that has went on? Words of wisdom?
