I’ve been on depo for 6 months.

I got my last shot 4 weeks ago.

All Last week I was bleeding. Dark brown.

Not enough for a tampon. But definitely enough to need to wear a liner. One small panty liner per day.

No other symptoms

Is this just breakthrough bleeding. Or should I worry about implantation bleeding.

I last had sex 5 weeks ago (one week before my shot was due) no pull out.
