Advice??

so I’m 17 days late but like I only had my period one time out of a whole year which was Nov 12th and it was a horrible horrific period and then I still haven’t gotten it again. 😭 like I keep feeling like I’m going to start and then nothing. Which I understand because I haven’t had a regular period in 1 year and I’m still EBF breastfeeding my daughter she will be a year old next month but still like shouldn’t I have gotten my period again? This month I’m almost a whole month late. But I don’t feel pregnant and we only had sex without a condom once and he pulled out! We always use condoms . We are absolutely not trying for another baby. I just need to know what’s going on and is this normal shouldn’t my period have returned?? I already have a 3 year old and a almost one year old I’m definitely not ready for another. Please no bashing.
