BFN!!! Waiting a few more days!!!

Today makes the 4th day with no AF I’ve been waiting before I took a test because sometimes im 1 or 2 days late. I couldn’t wait so today I got a test and took it as soon as I got home and it was BFN. I’m going to wait 2-3 more days and see if AF comes and if not then I’m going to test again. But my Dr. told me when I had my tubal a few years ago that if I got pregnant again that my levels may be to low to show on s pee test at home. A few months ago I was late and just thought that AF was going to start because like I said sometimes I’m a day or two late sometimes but it never did and I took a home pregnancy test and it came back positive but I had waited like a couple of weeks before I tested then and misscarried a few days later. So hopefully AF don’t come and when I test again in a few days I’ll get the results that I’ve been praying for!!!! Best of luck to everyone and lots of baby dust to us all!!! 🤞🤞🤞
