Diy tests aren't actual pregnancy tests, my love. Go to the market and buy an actual one for 88¢ or however much they're on the shelves for.

Take a real test. Though it’s only been a week and is probably too early to test. It’s also too early for all those symptoms.

First of all, it’s not “very likely” that you’re pregnant if you had sex a few days before your period was due. Assuming your period is regular, the likelihood of you ovulating a few days before your period is very slim. It’s usually around 14 days before your period that you ovulate.Secondly, definitely need an actual pregnancy test to figure this out. They’re so cheap at Walmart or the dollar store. And just as accurate as the expensive ones. But your period is likely late due to hormonal changes after sex if you haven’t been regularly having sex beforehand. Or a variety of other life changes/stressors.

6 days after sex would be too soon to even get a positive. DIY are not reliable, but you would have to wait a little longer before testing

Take a REAL test. At home chemistry tests do not work. Very likely you’re pregnant.
