Hey mommies. So I had my son almost a year ago and I breast until October. I had my period return in February (8mo pp), then light spotting for 5 ish days in March. I have now gone 67 days without any sort of AF or anything. Negative pregnancy tests. Is this normal? This didn't happen with my first baby but I also only carried her 25 weeks opposed to 37. The hubby and I want to TTC #3 but my body is crazy! HELP!!
