How soon did you know you were pregnant?

Hi ladies!

I’m 6 days late on my period and wondering if I could be pregnant? My husband and I aren’t trying but sometimes we don’t use protection the WHOLE time during sex, so there is a chance I could be.

I am typically very regular with my period coming every 28-30 days. There have been a few more stressful months that cause my period to delay, this month being a very stressful month as well.

However I have also been feeling extremely fatigued lately which has led me to question if I am pregnant, or if my hormones are out of whack.

How soon did y’all know you were pregnant? I am going to buy a pregnancy test soon but I know oftentimes pregnancy tests will come back negative in the beginning.
