No period, still negative

I stopped birth control mid-June. I had one totally normal 28 day cycle so I figured I was all back to normal with no side effects from stopping the b/c. My next cycle was 38 days which resulted in 10 days of testing like a crazy person since I'd never been late before. The best advice I can give is relax and buy the cheap tests on Amazon. I know if I say test once a week until you get your period you'll still test once a day so hopefully with the cheap tests you won't bankrupt yourself! Relax, your hormones are just sorting themselves out. Keep bd-ing every couple days in case you're ovulating later than expected too!
