Should I take a pregnancy test?

Flora

I gave birth in January. My son is 9 months and started getting a regular period again in May and this is the first month that it hasn’t come. It’s 12 days late and we don’t really use protection except the pull out method... I know...

Should I take a pregnancy test? I am a breastfeeding mom so idk if because of breastfeeding my period could not come for a reason.

Thanks
