Is this normal?

I take birth control- 21 day pill and 7 placebo. Been on it for almost 2 years.

Sexually active - use condoms too. (Haven’t had any accidents/breaks. Very good about taking the pill as well)

On about the 3-4th day of placebo pills I get my period. Was the same this cycle.

Flow started up slower then usual (was just lighter in color and flow), but got to the point where for almost 2 days it was fairly heavy and dark red. Was about a 2.5-3 day period.

I usually have 4-6 day cycles. Is this normal?

Edit- Should I be concerned about a change in Cycle length?

It also kinda abruptly ended- was heavy ish/dark then suddenly nothing. Didn’t taper off
