NO BASHING PLEASE.

I have an 8 month old son; when I went back for my 6 week check-up after having him, I started on birth control pills. My period has came on time every single month since then, except this last one. I am now 29 days late. I took three different brands of pregnancy tests and all of them were negative. I don't know if it is the birth control messing up the tests or what. I need some advice! 🤔
