Implantation

Aricka • IUI and IVF Warrior 🍍💉
Have any of you ladies had implantation bleeding in prior pregnancies? I had a positive OPK  cd 18 and think ovulation occurred on cd 19 I'm on cd 29 and just had spotting when I used the restroom this evening. But cd 29 is so close to my period I'm usually on a 32 day cycle so I'm not sure if it's just af or what. Thought and opinions much apriciated
