Worried it happened to fast👶🏻

I'm worried it happened to soon that it's not gonna stick.. I just stopped my pill in December I started taking prenatal shortly after & also started taking the vitamin Geritol woman on here was calling baby in a bottle i don't know if that was what helped so quickly but I'm pregnant with my 3rd well I guess 4th pregnancy I miss carried in 2005. So that is part of the worry I know I've had one so just hoping it sticks plus I've had a leap procedure in 2012. Anyway fingers crossed for a healthy happy 9 months doctors on 3-10 can't wait.. According to this app from my last period I'm 4wks 6days
