I have been breastfeeding my baby who is now one year old since he was born. My period returned in June so I had a June, July, & August period but missed when it was projected to be for September.. they were from June to July, 21 days, July to august 16 days. August to September so far now 28 days. I used to be a 21 day cycle. Is this normal or do I have to think about being pregnant again and take a test?? Thanks I am still breastfeeding so I am wondering if this is normal? Thanks
