Advice?

Sabrina

So, I’ve been on a birth control patch for two years and decided to stop like a month ago, well then I started to use the eve app to help me keep track of my period.. well I haven’t started my period at all and I was a little nervous so I took a pregnancy test and it came out negative? So idk what’s going on with my period? I’ve been on birth control for 7 years and I don’t know how normal my period is?
