What’s the best test?

Karrie

So I am 13 days late.. I had a miscarriage February 20th 2020 and since then my periods were regular (the 20th - 25th) each month since then except this month I didn’t get it. Im 13 days late today. I’m so scared and nervous 😬 I took a red dye dollar tree one 3 days ago and it said negative but still no sign of AF so idk honestly don’t have much money right now to spend on test after test idk I’m stressed but what do you recommend me do? 🤷🏼‍♀️
