Missed Period after stopping birth control

So I'm just wondering if anyone else has experienced this and if anyone has any advice. I stopped taking birth control at the end of October because me and my husband have started TTC and I had a period right away. I haven't had a period since. I know I'm not pregnant because I have taken about 12 tests and have had a doctor do a blood test to check and it came back negative. Has anyone skipped a period before  after stopping birth control and if so how long did it take you to get your period back. My glow says I'm on day 58 in my cycle now.
