Should i still take a test to be sure?

It’s my first time on low dose birth control pills. I had sex on the 10th day of taking them.

I had my withdrawal bleeding on the 6th day of my placebo week just in time because this app says I’d be having my period on Feb 29 and I did bleed.

Does having withdrawal bleeding mean I’m not pregnant? Should I still take a pregnancy test?

How long should withdrawal bleeding last?
