I really worried that my cycle is becoming irregular. Before I got pregnant with my son my cycle was super irregular. I would skip months at a time. My last cycle was over a week late and right now I'm on CD34 when my usual was a 29-29 day cycle. And if I don't start today I'm gonna hope it's cause I'm pregnant but I'm also worries that my cycle may be falling into its old habits
