3wks6days but so confused!

Shannon

So the app says I’m 3 weeks and 6 days today. I know not to always go off the app but I found out last weekend that I’m pregnant. How common is it to get a flaring positive 8 days before your missed period? Could I potentially be further along than the app says??

It sucks because my doctor won’t see me until I’m 8 weeks. Didn’t ask for a blood test or anything. This is my first pregnancy so I guess I don’t really know much. 🤷🏼‍♀️
