My husband and I are TTC but after going off Ortho Tri Cyclen lo 4 months ago my periods are extremely messed up. I cant really say irregular, b/c For instance I started on Dec. 5 bled for 9 days then started again on Dec. 23 bleeding for 8 days, and starting again on Jan. 15 which was 2 days ago and still going strong. I was only on the pill for 9 months, and my 'normal' cylce was 30 days with just 4 days of bleeding. I'm so confused about what to expect and when to expect ovulation. I've used Ovulation test strips and when I start using them, I only have a few days of pos. LH, then I start my period again. I'm getting pretty frustrated with the seemingly constant periods!! Any help out there would be much appreciated.
