My last period ended on January 12th. On January 24th I had sex and he pulled out so I took plan b a few hours later just to be sure.

From the 30th until the 1st, I had very light bleeding.

At first I thought it was my plan b pill giving me an early period because my normal period is due for the 4th. I’ve had breast tenderness as well that is pretty intense. The last time I took plan b it was this way. But I also thought it was a pms symptom too that I normally get.

But now I’m concerned that it might be implantation bleeding?

Am I overreacting? Or should I be concerned?
