Boobs hurt just a couple days after ovulations

💙Shadoe✨ • Just conceived our rainbow baby:) M/C in March 14 & chemical November 14... Going to marry the man of my dreams<3 After 14 months of trying finally got our BFP 8/7/15! Praying for a sticky baby🚼
I am just a few days past ovulation but Tuesday night i noticed my boobs hurt when i took my bra off. Yesterday all day they just felt heavy and really tender. I know its way to early but i took a preg test yesterday and it was negative as i expected... Could my boobs hurting like this be a sign that i may be pregnant, or probably just Af signs coming?
