Irregular periods suck

After being on the pill for 13 years I decided in january to come off to get my body used to not having that in my system to start. I have went to my doctor three times this year and I have to take progesterone to start. I am also going to a weight doctor and after taking b12 shots and losing 20 pounds I finally started on my own. Now I am over a month late negative pregnancy test even though I don't think I'm pregnant. I have missed a couple of weigh ins due to the holidays. Has anyone tried home remedies or anything else to help them start on their own and if so what are they and did they or did they not work. I am getting married in June and just want to have all my ducks in a row. Someone please help me out!
