Ok, So here is my info...I started my last cycle (after only 21 days) on Oct 16. So, if I were to have another 21 day cycle, I should start today. Before I had the IUD, I had normal 28 day cycles, no more, no less. I had the IUD removed and then did 1 month of BCP. I never started a cycle, so my dr put me on Provera, and I eventually started, thus the 21 day cycle. I just have no idea if I am going to have a 21 day cycle or a 28 day cycle, or something in between. Since my husband and I are wanting to get pregnant I REALLY want to take a HPT since I might would start today (and I haven't.) Does this make sense? I don't want to waste a HPT if I'm not supposed to start today. I am just confused. I hate it when I can't tell what my body is doing. I used to be so in tune with my body. I have still been charting my BBT. I know when the temperature dipped and then peaked. It has stayed at 98.2 for the last week. I am pretty sure that my hubby and I missed it this time around, but not knowing my cycle, I have no clue. Any suggestions or thoughts are greatly appreciated, and I hope everyone is doing great in their ttc!!
