I got off birth control in January 2018. I did not get my period until May 2018. I had two periods in July about 28 days apart. Now it is December 1, 2018, and I haven't had a period since July 20, 2018. I went to my doctor and got an ultra sounds and blood work (to test for pregnancy, hormones, thyroid)— she said that I am fine and just have irregular periods. Is anyone else like me? Should I get a second opinion.
