Absent periods

Hi ladies! My husband and I have a 2 year old boy and have been TTC for over a year for baby #2. I've taken countless tests, and gotten caught up with the obsession of having people tweak my tests to gain any hope in tests that are clearly negative. I have an appt this week to discuss the next stages in getting me on the right track to conceive again. But I'm just not having periods and not ovulating. I read into clomid and got hopeful, but know I need to have regular periods before that can be an option. Has anyone else had this issue? How did you gain a regular cycle again?
