Late period and pregnancy symptoms, bfing for 14 months

Cheyenne • I an 27 and I have a 3 year old boy, 6 year old boy, a 7 year old little girl, and 16 month old little girl

Just looking for insight. My period starting coming regularly in January after having my 3rd baby May 2019. It has been regular since then. I was supposed to get my period the 2nd and I still haven’t and no sign of it. I am still breastfeeding. I’m now 11 days late. I have gotten vvvfl lines on a few fre but nothing definitive. Having lots of pregnancy symptoms. Anyone else experienced anything like this? What was the outcome?
