Irregular period or test?

Lola

I've been off BC pill for about 3 months now

On the second month of being off it I had a period from July 24th to the 30th .

We don't use condoms but never finished inside.

<a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Period app</a> says I'm 4 days late and about two weeks ago I was in the hospital and not pregnant.

I need opinions and advice please ☺️
