Just want to start this off by saying I haven’t been pregnant or had a pregnancy scare or even had to worry about it for a long time, so forgive me if the answer to my question is obvious!

I had unprotected sex with my partner on February 13, and am now 5 days late for my period, which was supposed to start the 25th of February, and I’m always regular. Should I take a test or would it be too early for anything to be detected? Also does anyone think the month of February only being 28 days has anything to do with my period being so late?

TIA!
