Bleeding! Help!

Chloe

I am on the progestin only pill. I went 3-4 months without bleeding at all. But started bleeding just before Christmas around Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, and haven’t stopped at all yet. It’s been 26 days.

Should I be concerned ?!?!
