Post birthcontrol symptoms??

Summer • Girl mom• Wife 💍• Expecting

I have been on birth control for almost 3 years, and recently a little over a month almost two months ago I stopped taking my pills in order to start trying for a baby. Last month I got my period (what a downer), we continued to keep trying to conceive. I’ve read up on the after effects of birth control and how it could take time to ovulate regularly again, I was supposed to start my period this month around the 14-17 and it is now the 25, I took a test 4 days from the start of my missed period and then again on the 8th day, both tests coming out negative. Has this happened to anyone? Could it be a hormonal imbalance throwing my period off because my body is adjusting?
