Harder than I thought

Bre
So okay, I didn't have my period at all last month, besides ok Nov 15th I spotted for just that day, I dunno if that was suppose to be my period, or even ovulation, even down to implantation bleeding well to skip all that I took a pregnancy test this morning and it came back negative so I have no idea where's my period This is a whole new month and still nothing even though were only like 3 Days into December but to say November I didn't get one sign of my period so does anyone know what may be going on did I test too early or should I test again in the middle of the month if no period has arrived anyone feel free to answer I'm just a bit curious and what's going on honestly I really am beginning to think that I can't have kids it's been at least a year and 4 months now and still can't seem to find if I'm pregnant or not and I repeat but I took a test this morning and it came back negative last month no period at all
