Implantation bleeding.

I usually don't ask these kind of questions. But my period was supposed to start on the 28th. I been having spotting after having sex Sunday morning. . Like 6am is when it started. I thought it was my period but I'm not having any cramping.

My boobs have been so sore. Like you can barely touch them . That started when I ovulated. Which is normal and they usually get sore again when my period hits but they've been sore since ovulation. So this entire time. I was extremely emotional about a week ago. Still am.. but it's not a bad.

Anyway back to the spotting - it's a pinkish red. If I wear panty liners they would need changed often. But when I put a pad on, I practically don't bleed. And I see pink when I wipe.

What do you think ?

Plus me and my SO hardly ever use protection. Usually just withdrawal.
