Ugh I'm 33 days in my cycle. No period and no positive pregnancy test. I'm not sure if I tested too early or not since I ovulated late on day 21/22 of my cycle. But my cycles have also been anywhere from 28 days being the shortest to 37 being the longest but 30/32 days is usually the norm now. But because my cycles are so irregular after having my little boy 6 1/2 months ago. I don't know what to think or do. Does anyone have any advice?
