Breastfeeding mama's that have had a period...

Has your period skipped months or been pretty consistent. I got my period back at 9 weeks pp and have had one every month except this one. Currently 5 days late 🥴. It was a day or too late last month but I've NEVER been this late. Even before my pregnancies, it's always been like clockwork. I honestly don't think my husband and I had sex last month so I feel like I'm not pregnant. I also "felt" pregnant with all 3 pregnancies (even the ectopic) and I don't have that feeling this time but it's just weird that I havent gotten it yet. Just wanted to see if any other mamas had experienced this.
