Help, ovulation bleeding? Hopefully.

Hi all! So this is all according to the glow app. My period started on the 1st of this month an dended on the 4th. I had sex on the 17th...started ovulating on the 19th. Yesterday i had light light pink blood when i wiped and woke this morning to a darker spot of blood in my underwear. Havnt had anything since. I read implantation bleeding only happens right before your period, my period isnt due for another 17 days. I also started birth control this month. I have a 4 month old baby. What do yall think. Really hoping this is just ovulation bleeding
