I just recently (around 4pm today) tested and got peak fertility on a clearblue advanced test after 9 days. I know today and the next three days are most important to bd buuutt when will I most likely ovulate? I have herd anywhere between 12-36 hours. Is it possible I can miss the positive ovulation test if I don't constantly test? I only have 3 test strips left (non clearblue) and am so scared I won't ovulate or will miss it of I do. if I do test and get a negative is it possible I could have missed it? is it too late to start tracking bbt? I started at the being of my cycle but slowly gave up so I do have somewhat of a chart with constant temps
